+
+Tue Aug 22 16:51:22 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* valid.c: fixed a bug #203125 in Red hat bugzilla, crashing PHP4
+	  on validation errors, the heuristic to guess is a vctxt user
+	  pointer is the parsing context was insufficient.
+
+Mon Aug 21 10:40:10 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* doc/xmlcatalog.1 doc/xmlcatalog_man.xml doc/xmllint.1 doc/xmllint.xml:
+	  applied patch to man pages from Daniel Leidert and regenerated

+
+Tue Aug 15 15:02:18 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Applied the proposed fix for the documentation
+	  of xmlXPathCastToString(); see bug #346202.
+
+Tue Aug 15 14:49:18 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: While investigating bug #350247, I noticed
+	  that xmlSchemaIDCMatcher structs are massively recreated
+	  although only a maximum of 3 structs is used at the same
+	  time; added a cache for those structures to the
+	  validation context.
+
+Sat Aug 12 16:12:53 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* xmlschemas.c: applied patch from Marton Illes to fix an allocation

+
+Thu Jul 13 15:03:11 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlsave.c: Removed the automatic generation of CDATA sections
+	  for the content of the "script" and "style" elements when
+	  serializing XHTML. The issue was reported by Vincent Lefevre,
+	  bug #345147.
+	* result/xhtml1 result/noent/xhtml1: Adjusted regression test
+	  results due to the serialization change described above.
+
+Thu Jul 13 08:32:21 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* configure.in parser.c xmllint.c include/libxml/parser.h
+	  include/libxml/xmlversion.h.in: applied patch from Andrew W. Nosenko
+	  to expose if zlib support was compiled in, in the header, in the
+	  feature API and in the xmllint --version output.
+
+Thu Jul 13 08:24:14 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* SAX2.c: refactor to use normal warnings for entities problem
+	  and not straight SAX callbacks.
+
+Wed Jul 12 17:13:03 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed bug #347316, reported by David Belius:
+	  The simple type, which was the content type definition
+	  of a complex type, which in turn was the base type of a
+	  extending complex type, was missed to be set on this
+	  extending complex type in the derivation machinery.
+
+Mon Jul  3 13:36:43 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Changed xmlXPathCollectAndTest() to use
+	  xmlXPathNodeSetAddNs() when adding a ns-node in case of
+	  NODE_TEST_TYPE (the ns-node was previously added plainly
+	  to the list). Since for NODE_TEST_ALL and NODE_TEST_NAME
+	  this specialized ns-addition function was already used,
+	  I assume it was missed to be used with NODE_TEST_TYPE.
+
+Mon Jul  3 10:57:33 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* HTMLparser.c: applied const'ification of strings patch from
+	  Matthias Clasen
+
+Thu Jun 29 13:51:12 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* threads.c: patch from Andrew W. Nosenko, xmlFreeRMutex forgot to
+	  destroy the condition associated to the mutex.
+
+Thu Jun 29 12:48:00 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Fixed a double-free in xmlXPathCompOpEvalToBoolean(),
+	  revealed by a Libxslt regression test.
+
+Thu Jun 29 12:28:07 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Enhanced xmlXPathCompOpEvalToBoolean() to be also
+	  usable outside predicate evaluation; the intention is to
+	  use it via xmlXPathCompiledEvalToBoolean() for XSLT tests,
+	  like in <xsl:if test="/foo">.
+	  
+Wed Jun 28 19:11:16 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Fix a memory leak which occurred when using
+	  xmlXPathCompiledEvalToBoolean().
+
+Mon Jun 26 17:24:28 UTC 2006 William Brack <wbrack@mmm.com.hk>
+
+	* python/libxml.c, python/libxml.py, python/tests/compareNodes.py,
+	  python/tests/Makefile.am:
+	  Added code submitted by Andreas Pakulat to provide node
+	  equality, inequality and hash functions, plus a single
+	  test program to check the functions (bugs 345779 + 345961).
+
+Mon Jun 26 18:38:51 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Added xmlXPathCompiledEvalToBoolean() to the API and
+	  adjusted/added xmlXPathRunEval(), xmlXPathRunStreamEval(),
+	  xmlXPathCompOpEvalToBoolean(), xmlXPathNodeCollectAndTest()
+	  to be aware of a boolean result request. The new function
+	  is now used to evaluate predicates.
+
+Mon Jun 26 16:22:50 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Fixed an bug in xmlXPathCompExprAdd(): the newly
+	  introduced field @rewriteType on xmlXPathStepOp was not
+	  initialized to zero here; this could lead to the activation
+	  of the axis rewrite code in xmlXPathNodeCollectAndTest() when
+	  @rewriteType is randomly set to the value 1. A test
+	  (hardcoding the intial value to 1) revealed that the
+	  resulting incorrect behaviour is similar to the behaviour
+	  as described by Arnold Hendriks on the mailing list; so I
+	  hope that will fix the issue.	  
+
+Fri Jun 23 18:26:08 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Fixed an error in xmlXPathEvalExpr(), which
+	  was introduced with the addition of the d-o-s rewrite
+	  and made xpath.c unable to compile if XPATH_STREAMING
+	  was not defined (reported by Kupriyanov Anatolij -
+	  #345752). Fixed the check for d-o-s rewrite
+	  to work on the correct XPath string, which is ctxt->base
+	  and not comp->expr in this case.
+
+Mon Jun 19 12:23:41 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Added optimization for positional predicates
+	  (only short-hand form "[n]"), which have a preceding
+	  predicate: "/foo[descendant::bar][3]".
+
+Sun Jun 18 20:59:02 EDT 2006 Daniel Veillard <daniel@veillard.com>
+
+	* parser.c: try to fix the crash raised by the parser in
+	  recover mode as pointed by Ryan Phillips
+
+Sun Jun 18 18:44:56 EDT 2006 Daniel Veillard <daniel@veillard.com>
+
+	* python/types.c: patch from Nic Ferrier to provide a better type
+	  mapping from XPath to python
+
+Sun Jun 18 18:35:50 EDT 2006 Daniel Veillard <daniel@veillard.com>
+
+	* runtest.c: applied patch from Boz for VMS and reporting
+	  Schemas errors.
+
+Sun Jun 18 18:22:25 EDT 2006 Daniel Veillard <daniel@veillard.com>
+
+	* testapi.c: applied patch from Felipe Contreras when compiling
+	  with --with-minimum
+
+Fri Jun 16 21:37:44 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* tree.c include/libxml/tree.h: Fixed a bug in
+	  xmlDOMWrapAdoptNode(); the tree traversal stopped if the
+	  very first given node had an attribute node :-( This was due
+	  to a missed check in the traversal mechanism.
+	  Expanded the xmlDOMWrapCtxt: it now holds the namespace map
+	  used in xmlDOMWrapAdoptNode() and xmlDOMWrapCloneNode() for
+	  reusal; so the map-items don't need to be created for every
+	  cloning/adoption. Added a callback function to it for
+	  retrieval of xmlNsPtr to be set on node->ns; this is needed
+	  for my custom handling of ns-references in my DOM wrapper.
+	  Substituted code which created the XML namespace decl on
+	  the doc for a call to xmlTreeEnsureXMLDecl(). Removed
+	  those nastly "warnigns" from the docs of the clone/adopt
+	  functions; they work fine on my side.
+	  
+Mon Jun 12 13:23:11 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* result/pattern/namespaces: Adjusted the result of a
+	  regression test, since the fix of xmlGetNodePath() revealed a
+	  bug in this test result.
+
+Mon Jun 12 13:06:03 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* tree.c: Got rid of a compiler warning in xmlGetNodePath().
+
+Mon Jun 12 12:54:25 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* tree.c: Fixed xmlGetNodePath() to generate the node test "*"
+	  for elements in the default namespace, rather than generating
+	  an unprefixed named node test and loosing the namespace
+	  information.
+
+Fri Jun  9 21:45:02 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* include/libxml/parser.h: Clarified in the docs that the tree
+	  must not  be tried to be modified if using the parser flag
+	  XML_PARSE_COMPACT as suggested by Stefan Behnel
+	  (#344390).
+
+Tue Jun  6 17:50:43 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* configure.ini NEWS doc//* libxml.spec.in : preparing release of 2.6.26
+
+Tue Jun  6 17:25:23 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Fixed self-invented a segfault in xmlXPathCtxtCompile(),
+	  when the expression was not valid and @comp was NULL and I
+	  tried to do the d-o-s rewrite.
+
+Tue Jun  6 15:19:57 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* configure.ini NEWS doc//* libxml.spec.in : preparing release of 2.6.25
+
+Tue Jun  6 11:28:15 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Enabled the compound traversal again; I added a
+	  check to use this only if the have an expression starting
+	  with the document node; so in the case of "//foo", we
+	  already know at compilation-time, that there will be only
+	  1 initial context node. Added the rewrite also to
+	  xmlXPathEvalExpr().
+
+Tue Jun  6 10:23:10 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* xinclude.c: fix bug #343968, include='text' can't lead to a 
+	  recursion.
+
+Fri Jun  2 22:47:08 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Disabled the compound traversal for the release;
+	  I need first to assure that this is done only if we have
+	  1 initial node.
+
+Wed May 31 13:53:41 PST 2006 Aleksey Sanin <aleksey@aleksey.com>
+      
+	* xpath.c: fixed memory leak in xpath error reporting
+
+Wed May 31 15:30:16 CEST 2006 Daniel Veillard <daniel@veillard.com>
+
+	* libxml.h triodef.h: applied patch from Olli Savia for LynxOS
+
+Wed May 31 14:33:00 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c include/libxml/xpath.h runsuite.c:
+	  Changed the name of the recently added public function
+	  xmlXPathContextSetObjectCache() to
+	  xmlXPathContextSetCache(); so a more generic one, in
+	  case we decide to cache more things than only XPath
+	  objects.
+
+Tue May 30 21:36:16 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Optimized xmlXPathNodeCollectAndTest() and
+	  xmlXPathNodeCollectAndTestNth() to evaluate a compound
+	  traversal of 2 axes when we have a "//foo" expression.
+	  This is done with a rewrite of the XPath AST in
+	  xmlXPathRewriteDOSExpression(); I added an additional field
+	  to xmlXPathStepOp for this (but the field's name should be
+	  changed). The mechanism: the embracing descendant-or-self
+	  axis traversal (also optimized to return only nodes which
+	  can hold elements), will produce context nodes for the
+	  inner traversal of the child axis. This way we avoid a full
+	  node-collecting traversal of the descendant-or-self axis.
+	  Some tests indicate that this can reduce execution time of
+	  "//foo" to 50%. Together with the XPath object cache this
+	  all significantly speeds up libxslt.
+
+Tue May 30 11:38:47 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: A warning will now be reported in the value of
+	  the XSD attribute 'schemaLocation' does not consist of tuples
+	  (namespace-name, document-URI). A warning will be reported
+	  if a schema document could not be found at the specified
+	  location (via 'schemaLocation' or
+	  'noNamespaceSchemaLocation').
+	* include/libxml/xmlerror.h: Added XML_SCHEMAV_MISC to
+	  xmlParserErrors.
+
+Tue May 30 11:21:34 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Enhanced xmlXPathNodeCollectAndTest() to avoid
+	  recreation (if possible) of the node-set which is used to
+	  collect the nodes in the current axis for the currect context
+	  node. Especially for "//foo" this will decrease dramatically
+	  the number of created node-sets, since for each node in the
+	  result node-set of the evaluation of descendant-or-self::node()
+	  a new temporary node-set was created. Added node iterator
+	  xmlXPathNextChildElement() as a tiny optimization for
+	  child::foo.
+
+Mon May 29 18:06:17 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c include/libxml/xpath.h: Added an XPath object cache.
+	  It sits on an xmlXPathContext and need to be explicitely
+	  activated (or deactivated again) with
+	  xmlXPathContextSetObjectCache(). The cache consists of 5
+	  lists for node-set, string, number, boolean and misc XPath
+	  objects. Internally the xpath.c module will use object-
+	  deposition and -acquisition functions which will try to reuse
+	  as many XPath objects as possible, and fallback to normal
+	  free/create behaviour if no cache is available or if the cache
+	  is full.
+	* runsuite.c: Adjusted to deactivate the cache for XML Schema
+	  tests if a cache-creation is turned on by default for the whole
+	  library, e.g. for testing purposes of the cache. It is
+	  deactivated here in order to avoid confusion of the memory leak
+	  detection in runsuite.c.
+
+Wed May 24 10:54:25 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Removed a memcpy if xmlXPathNodeSetMerge(); it
+	  seems we really need to walk the whole list, since those
+	  nastly namespace nodes need to be added with
+	  xmlXPathNodeSetDupNs(); thus a pure memcpy is not possible.
+	  A flag on the node-set indicating if namespace nodes are in
+	  the set would help here; this is the 3rd flag which would
+	  be usefull with node-sets. The current flags I have in mind:
+	  1) Is a node-set already sorted?
+	     This would allow for rebust and optimizable sorting
+	     behaviour.
+	  2) Of what type are the nodes in the set (or of mixed type)?
+	     This would allow for faster merging of node-sets.
+	  3) Are namespace nodes in the set?
+	     This would allow to skipp all the namespace node specific
+	     special handling. Faster node-set merging if the first
+	     set is empty; just memcpy the set.
+
+Mon May 22 17:14:00 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Optimization of count(): eliminated sorting
+	  (see bug #165547). Optimization of XPATH_OP_FILTER if the
+	  predicate is a [1] (disable with XP_OPTIMIZED_FILTER_FIRST if
+	  it produces trouble). Tiny opt in xmlXPathNodeSetMerge().
+	  
+Mon May 22 13:33:12 CEST 2006 Rob Richards <rrichards@ctindustries.net>
+
+	* tree.c: Revert behavior change in xmlSetProp to handle attributes
+	  with colons in name and no namespace.
+
+Fri May 19 21:56:43 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Substituted all remaining calls to xmlXPathCmpNodes()
+	  for xmlXPathCmpNodesExt(). Tiny further enhancement of
+	  xmlXPathCmpNodesExt(). Added additional checks in various code
+	  parts to avoid calling sorting or merging functions if the
+	  node-set(s) don't need them; i.e., if they are empty or contain
+	  just one node.
+
+Fri May 19 13:16:58 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Optimized the comparison for non-element nodes
+	  in xmlXPathCmpNodesExt(); the comparison is used for sorting
+	  of node-sets. This enhancement is related to bug #165547.
+	  There are other places where the old comparison function
+	  xmlXPathCmpNodes() is still called, but I currently don't
+	  know exactly what those calls are for; thus if they can be
+	  substituted (if it makes sense) for the new function.
+
+Tue May 16 16:55:13 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xpath.c: Applied patch from Rob Richards, fixing a potential
+	  memory leak in xmlXPathTryStreamCompile(), when a list of
+	  namespaces was assigned to the XPath compilation context;
+	  here a new namespace list was created and passed to
+	  xmlPatterncompile(); but this list was not freed afterwards.
+	  Additionally we avoid now in xmlXPathTryStreamCompile() to
+	  compile the expression, if it has a colon - indicating
+	  prefixed name tests - and no namespace list was given. The
+	  streaming XPath mechanism needs a namespace list at
+	  compilation time (unlike normal XPath, where we can bind
+	  namespace names to prefixes at execution time).
+	* pattern.c: Enhanced to use a string dict for local-names,
+	  ns-prefixes and and namespace-names.
+	  Fixed xmlStreamPushInternal() not to use string-pointer
+	  comparison if a dict is available; this won't work, since
+	  one does not know it the given strings originate from the
+	  same dict - and they normally don't do, since e.g.
+	  namespaces are hold on xmlNs->href. I think this would be
+	  worth an investigation: if we can add a @doc field to xmlNs
+	  and put the @href in to a additionan namespace dict hold
+	  in xmlDoc. Daniel will surely not like this idea :-) But
+	  evaluation of tons of elements/attributes in namespaces
+	  with xmlStrEqual() isn't the way we should go forever.
+	  
+Thu May 11 18:03:49 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed bug #341337, reported by David Grohmann.
+	  The code expected a node (xmlNodePtr) on the info for a
+	  non-existent default attribute, which clearly cannot be
+	  expected, since the attribute does not exist. I can only
+	  guess that this sneaked trying to eliminate the query
+	  for the owner-element, which is unavoidable actually.
+	  Note that creation of default attributes won't have an
+	  effect if validating via SAX/XMLReader; i.e., the processor
+	  won't fire additional start-attribute events (I'm not even
+	  sure if Libxml2 has such a SAX-event; I think it hands them
+	  all over in the start-element event).
+
+Tue May  9 21:47:58 CEST 2006 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed bug #341150, reported by Michael Romer.
+	  In xmlSchemaBuildContentModelForSubstGroup(),

+	* xmlregexp.c: bug in xmlRegExecPushString2() pointed out by 
+	  Sreeni Nair.
+
+Tue Dec 20 16:55:31 CET 2005 Rob Richards <rrichards@ctindustries.net>
+
+	* tree.c: fix bug #322136 in xmlNodeBufGetContent when entity ref is 
+	  a child of an element (fix by Oleksandr Kononenko).
+	* HTMLtree.c include/libxml/HTMLtree.h: Add htmlDocDumpMemoryFormat.
+
+Tue Dec 20 11:43:06 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c xmlstring.c: Fixed a segfault during
+	  text concatenation when validating a node tree:
+	  xmlStrncat was called with a @len of -1; but unlike
+	  xmlStrncatNew, it does not calculate the length
+	  automatically in such a case (reported by Judy Hay
+	  on the mailing list).
+	  Updated the descriptions of the involved string
+	  functions to note this.
+
+Thu Dec 15 12:11:07 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* nanohttp.c: applied patch from Gary Coady to accept gzipped
+	  http resources.
+
+Wed Dec 14 18:41:26 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* win32/configure.js: Added enable/disable of runtime
+	  debugging (LIBXML_DEBUG_RUNTIME).
+
+Wed Dec 14 18:11:50 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* include/libxml/xmlversion.h.in: Fixed to define
+	  LIBXML_DEBUG_RUNTIME on the basis of @WITH_RUN_DEBUG@.
+
+Tue Dec 13 12:49:23 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* test/schemas/bug321475* result/schemas/bug321475*:
+	  Added regression test for bug #321475 (reported by
+	  Gabor Nagy). Fixing of bug #323510 seemed to have
+	  fixed this bug as well.
+
+Mon Dec 12 16:19:16 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* test/schemas/bug323510* result/schemas/bug323510*:
+	  Added regression test for bug #323510.
+
+Mon Dec 12 16:11:13 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Workaround for bug #323510 (reported by
+	  Jonathan Filiatrault): substituted the epsilon transition
+	  for a labelled transition, in order to avoid a bug in
+	  xmlregexp.c which eliminated the epsilon transition and
+	  marked the initial state as final.
+
+Mon Dec 12 14:25:46 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlreader.c: Gary Coady pointed a memory leak in
+	  xmlTextReaderReadInnerXml() applied patch fixing #323864
+
+Sat Dec 10 12:08:28 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* HTMLparser.c configure.in parserInternals.c runsuite.c runtest.c
+	  testapi.c xmlschemas.c xmlschemastypes.c xmlstring.c: fixed a number
+	  of warnings shown by HP-UX compiler and reported by Rick Jones
+
+Fri Dec  9 18:57:31 CET 2005 Rob Richards <rrichards@ctindustries.net>
+
+	* xmlwriter.c: Insert space between pubid and sysid when both 
+	  passed to xmlTextWriterStartDTD and indenting not being used.
+	  Remove no longer used Mem callbacks.
+
+Fri Dec  9 11:01:16 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* runsuite.c: Changed to instantly mark instance-tests as
+	  failed if the corresponding schema was invalid. This
+	  reflects the side of the Python code for the XML Schema test
+	  suite. We now get the same number of failed tests on both
+	  sides.
+
+Wed Dec  7 14:59:01 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlreader.c include/libxml/xmlreader.h: Added
+	  xmlTextReaderSchemaValidateCtxt() to the API.
+
+Wed Dec  7 12:59:56 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed a segfault: the instance document was
+	  still tried to be validated, if the schema, dynamically
+	  acquired using XSI was invalid, thus mangled. The
+	  validation will stop (or rather won't validate) now in
+	  such a case. The schema parser error code will be set
+	  on the validion context now; this is somehow not nice,
+	  but it assures that the validation context indicates an
+	  error in there was a parser error.
+
+Tue Dec  6 18:57:23 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlreader.c: small doc patch from Aron Stansvik
+	* legacy.c: another doc patch for a deprecated API
+
+Mon Dec  5 16:23:49 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* Makefile.am: Tiny change for 'make tests': raised
+	  the number of expected failures for James Clark's
+	  XML Schema datatype tests from 10 to 11. The additional
+	  reported error was agreed to be correct long time ago,
+	  but we missed to adjust the message reported by
+	  the testing script.
+
+Fri Dec  2 13:51:14 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* result/schemas/decimal* result/schemas/bug322411*:
+	  Added missing regression test results for the latest IDC
+	  and xs:decimal bugs.
+
+Wed Nov 30 12:22:23 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* test/schemas/decimal* test/schemas/bug322411*: Added
+	  regression tests for the latest IDC and xs:decimal bugs.
+
+Wed Nov 30 11:57:35 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed bubbling of duplicate IDC nodes: the
+	  parent's list of duplicates was filled with NULLs instead
+	  of the nodes under certain conditions. This lead to a
+	  segfault when the list's entries were accessed.
+
+Mon Nov 28 17:28:53 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemastypes.c: Fixed parsing of xs:decimal to
+	  allow/deny special lexical forms. Fixed the totalDigits
+	  for values in the range (x < 1) &&  (x > -1) && (x != 0);
+	  E.g "0.123" has now a totalDigits of 3 (was 4 previously).
+	  Adjusted the comparison function for decimals due to this
+	  change. As a side effect comparison against zeroes was
+	  optimized.
+
+Mon Nov 28 13:25:11 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: An assignment to a local variable, which was
+	  used to access the IDC node list, was missing after the
+	  reallocation of the list (reported by Fabrice GUY
+	  bug #322411). Renamed the define ENABLE_IDC_NODE_TABLES
+	  to ENABLE_IDC_NODE_TABLES_TEST and *disabled* it, since
+	  it is used to force bubbling of IDC node tables even
+	  if not necessary; this was intended to be used for test
+	  purposes, but I obviously missed to disable it (although
+	  it apparently helped finding the bug).
+
+Wed Nov 23 17:34:52 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: In xmlSchemaAssembleByXSI() the return value
+	  of xmlSchemaGetMetaAttrInfo() was not assigned to anything;
+	  this caused XSI-driven-dynamic schema acquisition to fail
+	  with @noNamespaceSchemaLocation (reported by Julien Lamy
+	  on the mailing list).
+
+Tue Nov 22 18:31:34 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed a bug in xmlSchemaFindRedefCompInGraph()
+	  which caused the search for components to stop at the
+	  first encountered attribute group component.
+	  Fixed error report in xmlSchemaCheckSRCRedefineFirst(): the
+	  designation of a not-found component was not reported.
+
+Mon Nov 21 12:23:28 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlschemastypes.c: Albert Chin found another signed/unsigned problem
+	  in the date and time code raised on IRIX 6.5
+
+Fri Nov 18 18:13:38 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c include/libxml/xmlschemas.h:
+	  Added xmlSchemaSetParserStructuredErrors() to the API.
+	  Fixed channeling of error relevant information to
+	  subsequent parser/validation contexts.
+
+Thu Nov 17 14:11:43 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* parserInternals.c: removed unreachable code pointed out by 
+	  Oleksandr Kononenko, fixes bug #321695
+
+Thu Nov 17 08:24:31 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* parser.c: use ctxt->standalone = -2 to indicate that the
+	  XMLDecl was parsed but no standalone attribute was found,
+	  suggested by Michael Day to detect if an XMLDecl was found.
+
+Tue Nov 15 09:49:24 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* runtest.c: Hisashi Fujinaka pointed that errors in Schemas tests
+	  were not properly reported.
+
+Sun Nov 13 13:42:41 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlIO.c: applied patch from Geert Jansen to remove xmlBufferClose()
+	  which is not needed.
+
+Fri Nov 11 13:48:52 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Changed xmlSchemaFormatIDCKeySequence()
+	  to use xmlSchemaGetCanonValueWhtspExt() in order to
+	  correctly report values for xs:anySimpleType.
+	* test/schemas/idc-keyref-err1*
+	  result/schemas/idc-keyref-err1*: Added a test for this change.
+
+Wed Nov  9 13:07:24 EST 2005 Rob Richards <rrichards@ctindustries.net>
+
+	* xmlIO.c xmlwriter.c: function consolidation when writing to xmlBuffer.
+	  Return error condition not len if xmlwriter fails writing to buffer.
+
+Wed Nov  9 09:54:54 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlsave.c xmlIO.c include/libxml/xmlIO.h include/libxml/xmlsave.h:
+	  applied patch from Geert Jansen to implement the save function to 
+	  a xmlBuffer, and a bit of cleanup.
+
+Mon Nov  7 14:58:39 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c xmlschemastypes.c: Fixed the type of the
+	  totalDigits value to be positiveInteger.
+	  Fixed crash in an error report function when we gave it
+	  the document node; only element and attribute nodes are
+	  processed now (reported by Rob Richards).
+
+Tue Nov  1 16:22:29 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlregexp.c: fix bug #319897, problem with counted atoms
+	  when the transition itself is counted too
+	* result/regexp/hard test/regexp/hard: augmented the regression
+	  tests with the problem exposed.
+
+Tue Nov  1 11:54:39 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* win32/Makefile.mingw include/win32config.h: applied patch from

+
+Fri Oct 28 17:58:13 CEST 2005 Daniel Veillard <daniel@veillard.com>

+
+Fri Oct 28 16:53:51 CEST 2005 Daniel Veillard <daniel@veillard.com>

+
+Sat Oct 22 10:00:41 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	* parser.c: fixed second spot where CRLF split between chunks

+	  and formal expressions tests)
+
+Fri Oct 21 10:50:14 EDT 2005 Rob Richards <rrichards@ctindustries.net>
+
+	* xmlsave.c: prevent output of fragment tags when serializing XHTML.
+
+Wed Oct 19 16:53:47 BST 2005 Daniel Veillard <daniel@veillard.com>

+	  the London airport.
+
+Thu Oct 20 12:54:23 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Removed creation of a temporary parser context
+	  during validation when processing xsi:type; this previously
+	  added a string to the dict of the schema - to assure thread
+	  safety, we don't want to modify a given schema during
+	  validation.
+
+Thu Oct 20 17:05:29 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	* xmlwriter.c: fixed problem in xmlTextWriterVSprintf caused by
+	  misuse of vsnprintf
+	* configure.in, config.h.in: added a configuration check for
+	  va_copy and added a define for VA_COPY for xmlwriter.c fix
+	* parser.c: fixed problem with CRLF split between chunks (bug
+	  #319279) (fix provided by Brion Vibber)
+
+Wed Oct 19 18:49:52 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed a potential memory leak in
+	  xmlSchemaCheckCSelectorXPath() when an internal error occurs.
+	  Fixed setting of ctxt->err to the given error code in
+	  the parsing error functions.
+	* pattern.c: Added internal xmlCompileIDCXPathPath() as a
+	  starting point for IDC XPath compilation; this and some other
+	  tiny changes fixes issues regarding whitespace in the
+	  expressions and IDC selector/field relevant restrictions of
+	  the subset of XPath. Fixed a missing blocking of attributes
+	  in xmlStreamPushInternal().
+
+Mon Oct 17 15:06:05 EDT 2005 Daniel Veillard <daniel@veillard.com>
+
+	* runtest.c: removed the error message
+	* relaxng.c xmlschemas.c: removed 2 instability warnings from function
+	  documentation
+	* include/libxml/schemasInternals.h: changed warning about API stability
+	* xmlregexp.c: trying to improve runtime execution of non-deterministic
+	  regexps and automata. Not fully finished but should be way better.
+
+Mon Oct 17 16:12:02 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed a memory leak in
+	  xmlSchemaContentModelDump(). Added output of local types
+	  in xmlSchemaElementDump(). Tiny cosmetical changes to the
+	  dump output.
+
+Mon Oct 17 14:29:08 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* tree.c pattern.c: Silenced intel compiler warnings (reported
+	  by Kjartan Maraas, bug #318517).
+	* xmlschemas.c: The above changes in pattern.c revealed an
+	  inconsistency wrt IDCs: we now _only_ pop XPath states, if
+	  we really pushed them beforehand; this was previously not
+	  checked for the case when we discover an element node to be
+	  invalid wrt the content model.
+	  Fixed segfault in xmlSchemaGetEffectiveValueConstraint().
+
+Fri Oct 14 16:40:18 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* result/schemas/*.err: Adapted regression test results.
+
+Fri Oct 14 16:21:22 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+	
+	* xmlschemas.c: Fixed some identity-constraint issues:
+	  Restructured IDC node-tables
+	  Allowed IDCs to resolve also to nodes of complex type with
+	  simple content.
+	  Added check for keyrefs with references to keyrefs.
+	  IDC target-nodes were interferring with IDC node-tables,
+	  since they used one list of entries only. I separated this
+	  one big list into 3 lists: 1 for IDC node-table entries,
+	  1 for _duplicates_ of IDC node-table entries and 1 for
+	  IDC target-nodes. More code, but cleaner and it works at last.
+	  Keyrefs will fail to resolve to duplicate key/unique entries.
+	  I thought this was already working this way, but it didn't.
+	  The wording of the definition for [node table] in the spec
+	  can lead to a scenario, where keyrefs resolve perfectly, even
+	  if the relevant key-sequences of the referenced key/unique have
+	  duplicates in the subtree. Currently only Saxon 8.5.1 is
+	  dissallowing resolution to duplicate entries correctly - we
+	  will follow Saxon here.
+	  Removed some intel compiler warnings (reported by
+	  Kjartan Maraas, bug #318517).
+	* pattern.c: Fixed an IDC-XPath problem when resolving to
+	  attributes.	  
+
+Mon Oct 14 01:15:14 CEST 2005 Rob Richards <rrichards@ctindustries.net>
+	* nanohttp.c include/wsockcompat.h: applied patch from Kolja Nowak 
+	  to use getaddrinfo() if supported in Windows build (bug# 317431).
+
+Mon Oct 10 15:33:48 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>

+
+	* xmlschemas.c include/libxml/schemasInternals.h
+	  include/libxml/xmlerror.h: Initial implementation for
+	  redefinitions; this still misses checks for restrictions
+	  of the content model of complex types.
+	  Fixed default/fixed values for attributes (looks like they
+	  did not work in the last  releases).
+	  Completed constraints for attribute uses.
+	  Seperated attribute derivation from attribute constraints.
+	  Completed constraints for attribute group definitions.
+	  Disallowing <import>s of schemas in no target namespace if the
+	  importing schema is a chameleon schema. This contradicts
+	  the way Saxon, Xerces-J, XSV and IBM's SQC works, but the
+	  W3C XML Schema WG, thinks it is correct to dissalow such
+	  imports.
+	  Added cos-all-limited constraints.
+	  Restructured reference resolution to model groups and element
+	  declarations.
+	  Misc cleanup.
+

+	  error report output has changed in most cases. Initial migration to
+	  functions usable by both, the parser and the validator. This should
+	  ease a yet-to-come XS construction API in the long term as well.

+	  reported on the mailing list by Pawel Palucha)
+
+Fri Apr  8 21:58:04 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Added substitution group constraints; changed
+	  the build of the pre-computed substitution groups. Channeled
+	  errors during xsi assembling of schemas to the validation
+	  context. Fixed a big memory leak, which occured when using
+	  IDCs: the precomputed value of attributes was not freed if
+	  the attribute did not resolve to an IDC field (discovered
+	  with the help of Randy J. Ray's schema, posted to the
+	  xmlschema-dev maling list).
+
+Fri Apr  8 13:22:01 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Added "Particle correct 2" to parsing of model groups.
+	  Added handling substitution groups inside <choice> and <sequence>;
+	  for <all> this is not supported yet. Changed circular checks for
+	  model groups definitions. "memberTypes" are processed at different
+	  levels now: component resolution first, construction later; this
+	  goes hand in hand with a global change to handle component
+	  resolution in a distinct phase. Fixed invalid default values for
+	  elements to mark the schema as invalid; this just resulted in an
+	  error report previously, but the schema was handled as valid.
+	  Separated the assignment of the model groups to referencing
+	  model group definition references (i.e. particles); this was
+	  needed to perform the circularity check for model group definitions.
+	  Added "Element Declaration Properties Correct (e-props-correct)"
+	  constraints. Separated component resolution for simple/complex
+	  types.
+	* include/libxml/schemasInternals.h: Added a flag for substitution
+	  group heads.

+
+	* xmlschemas.c: Added "Type Derivation OK (Complex)" constraints
+	  and anchored them in the "Element Locally Valid (Element)"
+	  constraints. This restricts the type substitution via "xsi:type".
+
+Tue Apr  5 13:10:06 CEST 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlschemas.c: patch from Matthew Burgess to improve some schemas
+	  facets validation messages.
+
+Sat Apr  2 12:48:41 CEST 2005 Daniel Veillard <daniel@veillard.com>
+
+	* doc/* configure.in NEWS: preparing release 2.6.19, updated docs and

+	  a pointer in the API.
+
+Fri Apr  1 17:54:22 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xstc/fixup-tests.py: A tiny script to fixup some of the schema
+	  files used for the tests.
+
+Fri Apr  1 17:33:50 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c include/libxml/schemasInternals.h

+	  Committing again, since the CVS server aborted.
+
+Fri Apr  1 15:29:27 CEST 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemastypes.c: Corrected 'length' facet validation for
+	  QNames and notations. Corrected xmlSchemaGetCanonValue: some
+	  data types did not return a value if already in normalized
+	  form.
+	* xmlschemas.c include/libxml/schemasInternals.h:
+	  Eliminated creation of structs for <restriction>, <extension>,
+	  <simpleContent>, <complexContent>, <list> and <union>: the
+	  information is now set directly on the corresponding simple/
+	  complex type. Added some more complex type constraints.
+	  Added facet derivation constraints. Introduced "particle"
+	  components, which seem to be really needed if applying
+	  constraints. Corrected/change some of the parsing functions.
+	  This is all a bit scary, since a significant change to the code.
+	* result/schemas/src-element2-*.err result/schemas/element-*.err:
+	  Adapted regression test results.
+
+Fri Apr  1 16:07:59 CEST 2005 Daniel Veillard <daniel@veillard.com>
+
+	* doc/apibuild.py doc/elfgcchack.xsl: revamped the elfgcchack.h 
+	  format to cope with gcc4 change of aliasing allowed scopes, had
+	  to add extra informations to doc/libxml2-api.xml to separate
+	  the header from the c module source.
+	* *.c: updated all c library files to add a #define bottom_xxx
+	  and reimport elfgcchack.h thereafter, and a bit of cleanups.
+	* doc//* testapi.c: regenerated when rebuilding the API
+
+Thu Mar 31 17:20:32 CEST 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlsave.c: fixed bug reported by Petr Pajas, in the absence of
+	  encoding UTF-8 should really be assumed. This may break if 
+	  the HTTP headers indicates for example ISO-8859-1 since this
+	  then becomes a well formedness error.

+
+Thu Mar 24 12:01:30 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed call to a facet error report: the type of
+	  the error was wrong, resulting in a segfault (bug #171220, reported
+	  by GUY Fabrice).
+
+Mon Mar 21 22:58:37 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>

+	in c14n relative namespaces check and add structured error messages
+	to c14n code
+
+Thu Mar 17 12:55:23 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Removed inheritance of "mixed" content type for
+	  short-hand restrictions of "anyType" (reported by Guy Fabrice
+	  to the mailing list). Added the namespace conversion (chameleon
+	  includes) for the base type reference of <restriction> and
+	  <extension>.
+	* test/schemas/bug152470_1.xsd: Adapted due to the above change
+	  of "mixed" inheritance.
+
+Thu Mar 17 11:03:59 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlschemas.c: fixed a = -> == error pointed by GUY Fabrice
+
+Wed Mar 16 22:53:53 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlschemas.c: more debug messages from Matthew Burgess
+	* xmlschemastypes.c: xmlSchemaValidateLengthFacet API missing check.
+
+Wed Mar 16 17:37:04 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemastypes.c: Aaaannnd putting back the previous changes done
+	  by Daniel, which I overwrote with the previous commit.
+
+Wed Mar 16 17:20:25 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c xmlschemastypes.c include/libxml/xmlschemastypes.h:
+	  Hopefully finished validation against facets to use the normalized
+	  value of both, the facets and instance values. Added 
+	  xmlSchemaValidateLengthFacetWhtsp(), xmlSchemaValidateFacetWhtsp()
+	  and xmlSchemaGetValType() to the schema API.
+
+Wed Mar 16 13:55:31 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* libxml.spec.in: do not package .la files
+	* xmllint.c: applied patch from Gerry Murphy for xmllint return code
+	* xmlschemastypes.c: fixed a couple of missing tests of parameters
+	  at public API entry points.
+
+Tue Mar 15 23:31:14 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	* xmlschemastypes.c: a couple of more changes to various
+	  decimal-handling routines.  Fixes python some problems
+	  turned up by the python tests.
+	* Makefile.am: change SchemasPythonTests message to warn
+	  that there are 10 'expected' errors (rather than 6) since
+	  we now reject a '+' sign on an unsigned.
+
+Tue Mar 15 15:43:27 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemastypes.c xmlschemastypes.h: In preparation to use
+	  normalized values of facets during validation: changed the
+	  arguments of some string comparison functions; added a static
+	  xmlSchemaValidateFacetInternal() with more arguments to be
+	  more flexible. Prepared XML_SCHEMA_FACET_ENUMERATION validation
+	  to use the comparison functions. Fixed some assignments in
+	  xmlSchemaValAtomicType(): total digit count, lo, mi, hi.
+
+Sun Mar 13 19:32:03 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* NEWS configure.in testapi.c doc/*: preparing release of 2.6.18
+	  updated docs and rebuilt

+
+Sat Mar 12 19:50:22 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* encoding.c: removed a static buffer in xmlByteConsumed(),

+
+Fri Mar 11 23:53:13 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	* xmlschemastypes.c: enhanced the parsing of XML_SCHEMAS_DECIMAL
+	  and much of the routine xmlSchemaCompareDecimals.  The
+	  changes were necessary to fix a problem reported on the
+	  mailing list by John Hockaday.
+
+Fri Mar 11 13:22:52 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: The schema parser will stop if components could
+	  not be resolved. This is not conforming to the spec but for now
+	  will avoid internal errors during type fixup and content model
+	  creation. Restructured inclusion/import of schemata: this avoids
+	  duplicate, self and circular inclusion. Chameleon includes are
+	  still workarounded. Added restriction to disallow references to
+	  non-imported namespaces. Corrected parsing of <group>.
+	* result/schemas/bug167754_0_0*: Added a missing test result.
+
+Thu Mar 10 16:02:17 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* doc/xml.html doc/encoding.html: Enriched encoding.html with more
+	  link and foreword warning to avoid problem with ignorant
+	  programmers, c.f #169721
+
+Thu Mar 10 15:01:34 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* python/tests/Makefile.am python/tests/readernext.py: added
+	  a regression test from Rob Richards for the previous bug
+
+Thu Mar 10 13:22:36 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlreader.c: applied fix for xmlTextReaderNext() bug from
+	  Rob Richards
+
+Thu Mar 10 11:35:57 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlmodule.c: second patch from Rick Jones, portability fix for
+	  HP-UX
+	* doc/examples/xpath1.c doc/examples/xpath2.c: first fix from Rick Jones
+	  to avoid warnings.
+
+Thu Mar 10 10:20:23 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* include/libxml/hash.h libxml.h libxml.spec.in: some gcc4 portability
+	  patches, including a serious aliasing bug exposed in s390 
+	  when trying to convert data pointer to code pointer.
+
+Mon Mar  7 18:34:00 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Tiny restructuring of the validation start-up
+	  functions. Added cleanup of the validation context at the
+	  end of validation. This takes care of the validation context
+	  being reused.
+
+Mon Mar  7 12:12:01 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemastypes.c: Tiny changes in the comparison functions
+	  I forgot to commit last time.
+
+Fri Mar  4 22:51:42 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Added IDC validation of anySimpleType attribute
+	  values; anyway the IDC key comparison is restricted to
+	  anySimpleType <--> string based types. For other types we
+	  would possibly need the canonical lexical representation of
+	  them; this sounds not performant, since we would need to
+	  build such a representation each time we want to compare against
+	  anySimpleType. TODO: think about buffering the canonical values
+	  somewhere. Fixed error reports for default attributes to work
+	  without a node being specified. This all and the enabling of IDC
+	  validation fixes bug #165346 (reported by Benoit Gr?goire - could
+	  not read his last name correctly from bugzilla).
+
+Fri Mar  4 18:57:44 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Enabled IDC parsing and validation.
+	* xmlschemastypes.c include/libxml/xmlschemastypes.h: 
+	  Added xmlSchemaCopyValue to the API; this was done due to
+	  validation of default attributes against IDCs: since IDC keys
+	  consume the precomputed value, one needs a copy.
+	* pattern.c: Enabled IDC support; this is currently done
+	  via calling xmlPatterncompile with a flag arg of 1.
+
+Wed Mar  2 11:45:18 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* Makefile.am doc/examples/Makefile.am python/tests/Makefile.am
+	  xstc/Makefile.am: try to fix a problem with valgrind.
+	* python/generator.py python/libxml.c python/tests/Makefile.am
+	  python/tests/tstmem.py: applied memory leak fix from Brent Hendricks
+	  c.f. bug #165349
+
+Mon Feb 28 11:18:24 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* tree.c: Changed xmlSearchNsByHref to call xmlNsInScope with
+	  the prefix instead of the namespace name.
+	* test/schemas/annot-err_0.xsd test/schemas/element-err_0.xsd:
+	  Adapted invalid values of the "id" attribute, since they are
+	  validated now.
+
+Fri Feb 25 08:31:16 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* threads.c: new version with fixes from Rob Richards

+	  of bugs in the writer
+
+Mon Feb 21 21:51:03 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	* xmlsave.c: fixed problem when XMLLINT_INDENT was empty (bug 168033).
+	* xpath.c: fixed compilation warning, no change to logic.
+	* xmlschemastypes.c: fixed compilation warning, no change to logic.
+
+Mon Feb 21 14:48:27 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlwriter.c: applied patch from Rob Richards to fix a problem with

+Mon Feb 21 11:41:41 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* pattern.c xpath.c: fixed remaining known bugs in the XPath streaming,
+	  and switched XPath to use it by default when possible
+
+Sat Feb 19 19:25:14 CET 2005 Daniel Veillard <daniel@veillard.com>

+	* xmlschemastypes.c: a bit of cleanup
+	* elfgcchack.h testapi.c doc/*: rebuilt the API the tests and
+	  the documentation as a result.
+
+Fri Feb 18 20:34:03 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* xmlreader.c include/libxml/xmlreader.h: applied patch from
+	  Aron Stansvik to add xmlTextReaderByteConsumed()
+	* testReader.c: added a test option
+	* xmlschemastypes.c: fix a lack of pointer checking in APIs
+
+Fri Feb 18 12:41:10 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* test/schemas/bug167754_0*: Added the regression test of Frans
+	  Englich for bug #167754.
+
+Fri Feb 18 12:31:49 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Started support for IDC resolution to default
+	  attributes. If building the content model for <all>: ensured
+	  to put element declarations and not the particles into the
+	  content model automaton (this was bug #167754, reported by
+	  Frans Englich).
+
+Thu Feb 17 22:31:58 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* pattern.c pattern.h: Some experimental addition for parsing
+	  of expressions and streamable validation.
+	  Added xmlStreamPushAttr to the API.
+
+Thu Feb 17 19:57:35 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Added validation for the attribute "id" in the
+	  schemata; doing this needed error report fixes for notations,
+	  facets and group. Changed NOTATION validation to work with the
+	  declared NOTATIONs in the schema; this does have no impact on
+	  the validation via the relaxng module.
+	* xmlschemastypes.c include/libxml/xmlschemastypes.h:
+	  Added xmlSchemaNewNOTATIONValue to the API to be able to do
+	  the NOTATION validation described above.
+	* test/schemas/element-err_0.xsd test/schemas/annot-err_0.xsd:
+	  Fixed the values of the "id" attributes, which were not validated
+	  previously.  
+
+Thu Feb 17 12:03:46 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Fixed comparison for default/fixed attribute
+	  values, if the type was 'xsd:string'. Changed the comparison
+	  for IDCs to use the whitespace aware comparison function.
+	* xmlschemastypes.c include/libxml/xmlschemastypes.h:
+	  Added xmlSchemaGetCanonValue, xmlSchemaNewStringValue and
+	  xmlSchemaCompareValuesWhtsp to the API. Added functions
+	  to compare strings with whitespace combinations of "preserve",
+	  "replace" and "collapse".
+
+Wed Feb 16 13:24:35 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Further work on IDCs, especially evaluation for
+	  attribute nodes.
+
+Wed Feb 16 01:19:27 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* encoding.c: fix the comment to describe the real return values
+	* pattern.c xpath.c include/libxml/pattern.h: lot of work on
+	  the patterns, pluggin in the XPath default evaluation, but
+	  disabled right now because it's not yet good enough for XSLT.
+	  pattern.h streaming API are likely to be changed to handle
+	  relative and absolute paths in the same expression.
+
+Tue Feb 15 15:33:32 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c: Added IDC evaluation for attribute nodes.
+	  Made 'nil'ed elements work. Added a specific error message
+	  for 'strict' attribute wildcards.
+	* include/libxml/xmlerror.h: Added an error code for
+	  wildcards.
+	* result/schemas/anyAttr-processContents-err1_0_0.err: Adapted.  
+
+Sun Feb 13 16:15:03 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	This change started out as a simple desire to speed up the
+	execution time of testapi.c, which was being delayed by
+	nameserver requests for non-existent URL's.  From there it
+	just sort of grew, and grew....
+	* nanohttp.c, nanoftp.c: changed the processing of URL's
+	  to use the uri.c routines instead of custom code.
+	* include/libxml/xmlerror.h: added code XML_FTP_URL_SYNTAX
+	* uri.c: added accepting ipV6 addresses, in accordance with
+	  RFC's 2732 and 2373 (TODO: allow ipV4 within ipV6)
+	* gentest.py, testapi.c: fixed a few problems with the
+	  testing of the nanoftp and nanohttp routines.

+
+	* xinclude.c: fixed xmlXIncludeParseFile to prevent
+	  overwriting XML_COMPLETE_ATTRS when setting pctxt->loadsubset
+	  (bug 166199)
+	* Makefile.am, python/tests/Makefile.am, xstc/Makefile.am: added
+	  code to add $(top_builddir)/.libs to LD_LIBRARY_PATH whenever
+	  PYTHONPATH is set, to assure new libxml2 routines are used.
+
+Fri Feb 11 22:20:41 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	* parser.c: fixed problem when no initial "chunk" was

+
+Fri Feb 11 18:37:22 HKT 2005 William Brack <wbrack@mmm.com.hk>
+

+
+Thu Jan 27 13:39:04 CET 2005 Kasimier Buchcik <libxml2-cvs@cazic.net>
+
+	* xmlschemas.c include/libxml/schemasInternals.h:
+	  Added an initial skeleton for indentity-constraints. This is all
+	  defined out, since not complete, plus it needs support from other
+	  modules.
+	  Added machanism to store element information for the
+	  ancestor-or-self axis; this is needed for identity-constraints
+	  and should be helpfull for a future streamable validation.
+	* include/libxml/xmlerror.h: Added an error code for
+	  identity-constraints.
+
+Wed Jan 26 01:03:37 CET 2005 Daniel Veillard <daniel@veillard.com>

+
+Sat Jan 22 00:40:31 CET 2005 Daniel Veillard <daniel@veillard.com>
+
+	* dict.c parser.c include/libxml/dict.h: a single lock version
+	  mostly avoid the cost penalty of the lock in case of low

+Sun Jan  2 17:51:18 HKT 2005 William Brack <wbrack@mmm.com.hk>
+
+	Re-examined the problems of configuring a "minimal" library.
+	Synchronized the header files with the library code in order
+	to assure that all the various conditionals (LIBXML_xxxx_ENABLED)
+	were the same in both.  Modified the API database content to more
+	accurately reflect the conditionals.  Enhanced the generation
+	of that database.  Although there was no substantial change to
+	any of the library code's logic, a large number of files were
+	modified to achieve the above, and the configuration script
+	was enhanced to do some automatic enabling of features (e.g.
+	--with-xinclude forces --with-xpath).  Additionally, all the format
+	errors discovered by apibuild.py were corrected.
+	* configure.in: enhanced cross-checking of options
+	* doc/apibuild.py, doc/elfgcchack.xsl, doc/libxml2-refs.xml,
+	  doc/libxml2-api.xml, gentest.py: changed the usage of the
+	  <cond> element in module descriptions
+	* elfgcchack.h, testapi.c: regenerated with proper conditionals
+	* HTMLparser.c, SAX.c, globals.c, tree.c, xmlschemas.c, xpath.c,
+	  testSAX.c: cleaned up conditionals
+	* include/libxml/[SAX.h, SAX2.h, debugXML.h, encoding.h, entities.h,
+	  hash.h, parser.h, parserInternals.h, schemasInternals.h, tree.h,
+	  valid.h, xlink.h, xmlIO.h, xmlautomata.h, xmlreader.h, xpath.h]:
+	  synchronized the conditionals with the corresponding module code
+	* doc/examples/tree2.c, doc/examples/xpath1.c, doc/examples/xpath2.c:
+	  added additional conditions required for compilation
+	* doc/*.html, doc/html/*.html: rebuilt the docs
+	
+Sat Dec 25 18:10:02 HKT 2004 William Brack <wbrack@mmm.com.hk>
+
+	* parserInternals.c: fixed to skip (if necessary) the BOM for
+	  encoding 'utf-16'.  Completes the fix for bug #152286.
+	* tree.c, parser.c: minor warning cleanup, no change to logic
+	
+Fri Dec 24 16:31:22 HKT 2004 William Brack <wbrack@mmm.com.hk>
+
+	* python/generator.py: added most required entires to
+	  foreign encoding table, plus some additional logic to
+	  assure only the 1st param uses the 't#' format.  Fixes
+	  bug #152286, but may still have some other UTF-16 problems.
+
+Thu Dec 23 23:44:08 HKT 2004 William Brack <wbrack@mmm.com.hk>
+
+	* Makefile.am, gentest.py: enhanced for enabling build in
+	  a different directory.  Added (optional) param to gentest.py
+	  to specify the source directory (bug #155468)
+	* doc/Makefile.am: changed destination of NEWS from (top_srcdir)
+	  to (top_builddir) (bug #155468)
+	* python/Makefile.am, python/generator.py: enhanced for enabling
+	  build in a different directory(bug #155468).  Added (optional)
+	  param to generator.py to specify the source directory.  Added
+	  a new table of functions which have possible "foreign" encodings
+	  (e.g. UTF16), and code to use python 't' format instead of
+	  'z' format (mostly solving bug #152286, but still need to
+	  populate the table).
+	  
+Tue Dec 21 08:10:44 MST 2004 John Fleck <jfleck@inkstain.net>

+
+	* xmlschemas.c: Moved execution of xmlSchemaCheckDefaults to
+	  xmlSchemaTypeFixup; this ensures facets of inherited types to be
+	  checked prior to facets of derived types - which caused a seg

+
+Tue Mar 19 12:15:20 CET 2002 Daniel Veillard <daniel@veillard.com>

+	  was not serializing 1 as "1" if LC_ALL=sv_SE :-( and in the
+	  context of ScrollKeeper, made sure that if the number is
+	  an integer, the serialization follows the description at
+	  http://www.w3.org/TR/xpath#section-String-Functions
+
+Mon Mar 18 19:18:13 CET 2002 Daniel Veillard <daniel@veillard.com>

+	* doc/*: updated and rebuilt the web site

+	  the Windows and Cygwin maintainers.
+	* parser.c: humm, changed the way the SAX parser work when

+	  is that Python includes are real crap.
+
+Fri Mar 15 19:41:25 CET 2002 Daniel Veillard <daniel@veillard.com>
+
+	* configure,in: it was reported quite a few times that
+	  xml2-config --cflags should not output
+	  -I$includeprefix/libxml2/libxml because libxml2 header names
+	  clashes with existing names like list.h from C++ stl.
+	  Includes should be #include<libxml/xxx.h> so ...

+	  module based on the same code. The initialization is however
+	  different the 2 .so files fo libxml2 and libxslt are identical and
+	  they entry point initialize both libraries. this is done to avoid
+	  some possible nasty problem since the Python don't merge the maps
+	  of all shared modules.

+
+	* test/* : updated the examples, most of them were not well
+	           formed (humm), and added rdf2.
+	* result/* : resulting changes in the output.
+
+Sun Dec  6 13:06:58 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.c: changed the behaviour of xmlGetProp on NULL values.
+
+Sat Dec  5 12:25:09 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.c: patched a bug in the generation of empty attributes
+
+Fri Nov 27 01:36:54 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* entities.[ch], tree.[ch], tester.c: added copy interfaces
+	  for node/trees/documents/... Biggest problem is namespace
+	  support when copying subtrees.
+
+Sun Nov 15 19:59:47 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.c, entities.c: improve entities and char ref encoding,
+	  and cleanups of error messages.
+
+Fri Nov 13 13:03:10 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.c, entities.c: simple bug hunting done during rpm2html and
+	  rpmfind integration.
+
+Sun Nov  8 13:11:07 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.[ch]: Added interfaces allowing to specify a SAX
+	  handler before parsing.
+
+Sun Nov  8 09:39:17 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.c: redirrect all errors reporting through the SAX
+	  error function
+
+Wed Nov  4 14:21:54 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* entities.c: rather use HAVE_SNPRINTF and not depend on glib
+	* libtool, tlmain ...: update of the libtool files
+
+1998-11-04  Miguel de Icaza  <miguel@nuclecu.unam.mx>
+
+	* entities.c: Use g_snprintf insteda of snprintf.
+
+Sun Nov  1 14:31:06 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* entities.c, parser.c: debug and cleanup of CharRef handling/saving.
+	  added ent5 test for this purpose.
+	* parser.c, parser.h: formatting, comments and UTF-8 planning.
+
+Fri Oct 30 01:36:52 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.c: fixed? a strange error due to compression on a GWP
+	  document.
+
+Thu Oct 29 00:48:45 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.[ch]: bug fixing
+	* entities.[ch]: defined a specific type for predefined entities
+	* doc/xml.html: more documentation on the library, how to use it,
+	  overview of the interfaces.
+
+Wed Oct 28 17:56:35 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.[ch]: more cleanup on the API, made the tree mor conformant.
+
+Tue Oct 27 17:54:00 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.c: corrected a small bug
+	* doc/xml.html: continuing writing documentation.
+
+Tue Oct 27 17:54:00 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* debugXML.h debugXML.c: added debugging utilities.
+	* tester.c: added --debug switch.
+	* tree.c: patched an incorrect node->type assignment.
+	* parser.c: formatting, ensure that node->doc != NULL in attributes
+
+Tue Oct 27 01:15:39 EST 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.[ch] SAX.c tree.[ch]: large amount of changes to improve
+	  entity support and provide an internal representation close to
+	  DOM one (entity ref nodes, and attribute value as tree). I tried
+	  to preserve the interface but this will surely break some apps
+	  (I have to change rpm2html/rpmfind for example). I had to change
+	  two interfaces, and the generated tree is somewhat different.
+	* doc/* : started documenting the XML library, the tree and
+	  DOM/Corba. This is a first step.
+
+Sat Oct 24 14:23:51 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.c: Set up the fonctions comment block, boring but useful.
+	* parser.h, SAX.c, parser.c: now attributes are processed through
+	  the SAX interface. The problem is that my SAX interface diverged
+	  quite a bit from the original one, well this is not an official
+	  spec, and translating it from Java to C is hairy anyway...
+
+Tue Oct 20 02:11:21 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* SAX.c, entities.c, tree.c, encoding.c, error.c: Set up the
+	  fonctions comment block, boring but useful.
+
+Sun Oct 18 20:40:58 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* encoding.[ch], Makefile.am: Added the UTF-8, UTF-16 and ISO Latin 1
+	  conversion routines. However they are not yet used to convert the
+	  inputs. The core will run with UTF-8.
+
+Sun Oct 18 15:08:19 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.c : make sure that the type id is properly set-up when
+	  a new object is allocated, needed for DOM.
+
+Sat Oct 17 02:43:21 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.h, tree.c: Ok, the main objects in the tree will be native
+	  corba objects, it costs 8 bytes per Node, Attribute and Document
+	  but it simplifies the Corba integration a lot (no extra interface
+	  objects to allocate/free).
+
+Tue Oct 13 21:46:57 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.h, tree.c, parser.c: added prev and doc pointers to Node,
+	  and changed NODEs contants for conformity with DOM Level 1
+
+Wed Oct  7 23:42:46 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* added hooks to keep track of servants when creating objects
+	  xmlDoc and xmlNode (for Corba export).
+
+Sun Oct  4 03:18:09 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* added xml-config script.
+
+Thu Oct  1 16:22:37 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* autogen.sh : applied patch from Frederic Devernay <devernay@istar.fr>
+	  to autoupdate libtool and automake conf files.
+
+1998-09-30  Miguel de Icaza  <miguel@nuclecu.unam.mx>
+
+	* Makefile.am: Use '?' to separate the sed
+	commands as ',' is used when people pass -Wl,something.
+
+Thu Sep 24 15:13:29 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* tree.c, tree.h: added a per-document compression interface.
+
+Tue Sep 22 20:47:38 EDT 1998
+
+	* tree.c, tree.h: added saving with compression and added interfaces
+	  to control the compression level (xmlGetCompressMode,
+	  xmlSetCompressMode) and a new save to filename function (xmlSaveFile).
+
+Mon Sep 21 20:11:13 EDT 1998 Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* parser.c: corrected a loop for files of size 0
+
+1998-08-20  Raja R Harinath  <harinath@cs.umn.edu>
+
+	* error.h: New file.  Contains prototyes from `error.c'.
+
+Thu Aug 13 19:02:34 1998  Tom Tromey  <tromey@cygnus.com>
+
+	* Makefile.am (xmlincdir): New macro.
+	(xmlinc_HEADERS): Renamed from include_HEADERS.
+
+Thu Aug 13 00:40:14 EDT 1998  Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* applied small patch on numeric entities from
+	  Christopher Blizzard <blizzard@appliedtheory.com>
+
+Wed Aug 12 23:12:58 EDT 1998  Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* New release 0.2, removed the old xml_* files so that it's
+	    coherent with the other CVS base (W3C), far better conformance
+	    to standard, new namespaces, decent entities support, beginning
+	    of a SAX-like interface. Nearly nothing left intact, even the
+	    test examples ...
+
+1998-07-30  Christopher Blizzard  <blizzard@appliedtheory.com>
+
+	* .cvsignore: Add .deps dir
+
+Sun Jul 26 17:29:52 EDT 1998  Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* xml_tree: changed the memory allocation scheme for name in xmlNewNode
+
+Sun Jul 26 00:17:51 EDT 1998  Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* configure.in: added test for CPP
+	* AUTHORS, Changelog: the original ones didn't get commited but the
+	    glib ones instead, fixed.
+	* Makefile.am: corrected an error in library naming
+
+Fri Jul 24 16:47:14 1998  Daniel Veillard <Daniel.Veillard@w3.org>
+
+	* integrated code developped at W3C
+	* changed the original Copyright
+	* migrated to automake
+	* prefixed the filenames by xml_ to avoid filename clashes

+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+

+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+   - Increased the library modularity, far more options can be stripped out,
+    a --with-minimum configuration will weight around 160KBytes
+   - Use per parser and per document dictionnary, allocate names and small
+    text nodes from the dictionnary

+    provides namespace resolution and defaulted attributes, minimize memory
+    allocations and copies, namespace checking and specific error handling,
+    immutable buffers, make predefined entities static structures, etc...
+   - rewrote all the error handling in the library, all errors can be
+    intercepted at a structured level, with precise information
+  available.
+   - New simpler and more generic XML and HTML parser APIs, allowing to
+    easilly modify the parsing options and reuse parser context for multiple
+    consecutive documents.

+    declarations
+   - added xml2-config --libtool-libs option from Kevin P. Fleming
+   - a lot of profiling and tuning of the code, speedup patch for
+    xmlSearchNs() by Luca Padovani. The xmlReader should do far less
+    allocation and it speed should get closer to SAX. Chris Anderson worked
+    on speeding and cleaning up repetitive checking code.

+   - started adding routines to access xml parser context options
+
+
+2.2.1: July 21 2000:
+   - a purely bug fixes release
+   - fixed an encoding support problem when parsing from a memory block
+   - fixed a DOCTYPE parsing problem
+   - removed a bug in the function allowing to override the memory
+    allocation routines
+
+
+2.2.0: July 14 2000:
+   - applied a lot of portability fixes
+   - better encoding support/cleanup and saving (content is now always
+    encoded in UTF-8)
+   - the HTML parser now correctly handles encodings
+   - added xmlHasProp()
+   - fixed a serious problem with &#38;
+   - propagated the fix to FTP client
+   - cleanup, bugfixes, etc ...
+   - Added a page about libxml Internationalization
+    support
+
+
+1.8.9:  July 9 2000:
+   - fixed the spec the RPMs should be better
+   - fixed a serious bug in the FTP implementation, released 1.8.9 to solve
+    rpmfind users problem
+
+
+2.1.1: July 1 2000:
+   - fixes a couple of bugs in the 2.1.0 packaging
+   - improvements on the HTML parser
+
+
+2.1.0 and 1.8.8: June 29 2000:
+   - 1.8.8 is mostly a commodity package for upgrading to libxml2 according
+    to new instructions. It fixes a nasty problem
+    about &#38; charref parsing
+   - 2.1.0 also ease the upgrade from libxml v1 to the recent version. it
+    also contains numerous fixes and enhancements:
+    added xmlStopParser() to stop parsing
+      improved a lot parsing speed when there is large CDATA blocs
+      includes XPath patches provided by Picdar Technology
+      tried to fix as much as possible DTD validation and namespace
+        related problems
+      output to a given encoding has been added/tested
+      lot of various fixes

+   - output to a given encoding has been added/tested
+   - lot of various fixes
+
+
+2.0.0: Apr 12 2000:
+   - First public release of libxml2. If you are using libxml, it's a good
+    idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially
+    scheduled for Apr 3 the release occurred only on Apr 12 due to massive
+    workload.
+   - The include are now located under $prefix/include/libxml (instead of
+    $prefix/include/gnome-xml), they also are referenced by
+    #include <libxml/xxx.h>
+    instead of
+    #include "xxx.h"
+  
+   - a new URI module for parsing URIs and following strictly RFC 2396
+   - the memory allocation routines used by libxml can now be overloaded
+    dynamically by using xmlMemSetup()
+   - The previously CVS only tool tester has been renamed
+    xmllint and is now installed as part of the libxml2
+    package
+   - The I/O interface has been revamped. There is now ways to plug in
+    specific I/O modules, either at the URI scheme detection level using
+    xmlRegisterInputCallbacks()  or by passing I/O functions when creating a
+    parser context using xmlCreateIOParserCtxt()
+   - there is a C preprocessor macro LIBXML_VERSION providing the version
+    number of the libxml module in use
+   - a number of optional features of libxml can now be excluded at
+    configure time (FTP/HTTP/HTML/XPath/Debug)
+
+
+2.0.0beta: Mar 14 2000:
+   - This is a first Beta release of libxml version 2
+   - It's available only fromxmlsoft.org
+    FTP, it's packaged as libxml2-2.0.0beta and available as tar and
+  RPMs
+   - This version is now the head in the Gnome CVS base, the old one is
+    available under the tag LIB_XML_1_X
+   - This includes a very large set of changes. From a  programmatic point
+    of view applications should not have to be modified too much, check the
+    upgrade page
+   - Some interfaces may changes (especially a bit about encoding).
+   - the updates includes:
+    fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly
+        handled now
+      Better handling of entities, especially well-formedness checking
+        and proper PEref extensions in external subsets
+      DTD conditional sections
+      Validation now correctly handle entities content
+      change
+        structures to accommodate DOM
+    
+   - fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly

+   - DTD conditional sections
+   - Validation now correctly handle entities content
+   - change
+        structures to accommodate DOM
+   - Serious progress were made toward compliance, here are the result of the test against the
+    OASIS testsuite (except the Japanese tests since I don't support that
+    encoding yet). This URL is rebuilt every couple of hours using the CVS
+    head version.
+
+
+1.8.7: Mar 6 2000:
+   - This is a bug fix release:
+   - It is possible to disable the ignorable blanks heuristic used by
+    libxml-1.x, a new function  xmlKeepBlanksDefault(0) will allow this. Note
+    that for adherence to XML spec, this behaviour will be disabled by
+    default in 2.x . The same function will allow to keep compatibility for
+    old code.
+   - Blanks in <a>  </a> constructs are not ignored anymore,
+    avoiding heuristic is really the Right Way :-\
+   - The unchecked use of snprintf which was breaking libxml-1.8.6
+    compilation on some platforms has been fixed
+   - nanoftp.c nanohttp.c: Fixed '#' and '?' stripping when processing
+  URIs
+
+
+1.8.6: Jan 31 2000:
+   - added a nanoFTP transport module, debugged until the new version of rpmfind can use
+    it without troubles
+
+
+1.8.5: Jan 21 2000:
+   - adding APIs to parse a well balanced chunk of XML (production [43] content of the
+    XML spec)
+   - fixed a hideous bug in xmlGetProp pointed by Rune.Djurhuus@fast.no
+   - Jody Goldberg <jgoldberg@home.com> provided another patch trying
+    to solve the zlib checks problems
+   - The current state in gnome CVS base is expected to ship as 1.8.5 with
+    gnumeric soon
+
+
+1.8.4: Jan 13 2000:
+   - bug fixes, reintroduced xmlNewGlobalNs(), fixed xmlNewNs()
+   - all exit() call should have been removed from libxml
+   - fixed a problem with INCLUDE_WINSOCK on WIN32 platform
+   - added newDocFragment()
+
+
+1.8.3: Jan 5 2000:
+   - a Push interface for the XML and HTML parsers
+   - a shell-like interface to the document tree (try tester --shell :-)
+   - lots of bug fixes and improvement added over XMas holidays
+   - fixed the DTD parsing code to work with the xhtml DTD
+   - added xmlRemoveProp(), xmlRemoveID() and xmlRemoveRef()
+   - Fixed bugs in xmlNewNs()
+   - External entity loading code has been revamped, now it uses
+    xmlLoadExternalEntity(), some fix on entities processing were added
+   - cleaned up WIN32 includes of socket stuff
+
+
+1.8.2: Dec 21 1999:
+   - I got another problem with includes and C++, I hope this issue is fixed
+    for good this time
+   - Added a few tree modification functions: xmlReplaceNode,
+    xmlAddPrevSibling, xmlAddNextSibling, xmlNodeSetName and
+    xmlDocSetRootElement
+   - Tried to improve the HTML output with help from Chris Lahey
+
+
+1.8.1: Dec 18 1999:
+   - various patches to avoid troubles when using libxml with C++ compilers
+    the "namespace" keyword and C escaping in include files
+   - a problem in one of the core macros IS_CHAR was corrected
+   - fixed a bug introduced in 1.8.0 breaking default namespace processing,
+    and more specifically the Dia application
+   - fixed a posteriori validation (validation after parsing, or by using a
+    Dtd not specified in the original document)
+   - fixed a bug in
+
+
+1.8.0: Dec 12 1999:
+   - cleanup, especially memory wise
+   - the parser should be more reliable, especially the HTML one, it should
+    not crash, whatever the input !
+   - Integrated various patches, especially a speedup improvement for large
+    dataset from Carl Nygard,
+    configure with --with-buffers to enable them.
+   - attribute normalization, oops should have been added long ago !
+   - attributes defaulted from DTDs should be available, xmlSetProp() now
+    does entities escaping by default.
+
+
+1.7.4: Oct 25 1999:
+   - Lots of HTML improvement
+   - Fixed some errors when saving both XML and HTML
+   - More examples, the regression tests should now look clean
+   - Fixed a bug with contiguous charref
+
+
+1.7.3: Sep 29 1999:
+   - portability problems fixed
+   - snprintf was used unconditionally, leading to link problems on system
+    were it's not available, fixed
+
+
+1.7.1: Sep 24 1999:
+   - The basic type for strings manipulated by libxml has been renamed in
+    1.7.1 from CHAR to xmlChar. The reason
+    is that CHAR was conflicting with a predefined type on Windows. However
+    on non WIN32 environment, compatibility is provided by the way of  a
+    #define .
+   - Changed another error : the use of a structure field called errno, and
+    leading to troubles on platforms where it's a macro
+
+
+1.7.0: Sep 23 1999:
+   - Added the ability to fetch remote DTD or parsed entities, see the nanohttp module.
+   - Added an errno to report errors by another mean than a simple printf
+    like callback
+   - Finished ID/IDREF support and checking when validation
+   - Serious memory leaks fixed (there is now a memory wrapper module)
+   - Improvement of XPath
+    implementation
+   - Added an HTML parser front-end

+   Instructions for standalone test regressions of libxml2
+
+libxml2-tests-$version.tar.gz contains 3 standalone C programs as well
+as a large amount of tests and results coming from libxml2 itself and
+from W3C, NIST, Sun Microsystems, Microsoft and James Clark. Each C
+program has a different testing purpose:
+
+  runtest.c : runs libxml2 basic internal regression tests
+  runsuite.c: runs libxml2 against external regression tests
+  testapi.c : exercises the library public entry points
+  testchar.c: exercise the check of character ranges and UTF-8 validation
+
+The command:
+
+  make -f Makefile.tests check
+
+should be sufficient on an Unix system to build and exercise the tests
+for the version of the library installed on the system. Note however
+that there isn't backward compatibility provided so if the installed
+version is older to the testsuite one, failing to compile or run the tests
+is likely. In any event this won't work with an installed libxml2 older
+than 2.6.20.
+Building on other platfroms should be a matter of compiling the C files
+like any other program using libxml2, running the test should be done
+simply by launching the resulting executables.

+
+           TODO for the XML parser and stuff:
+	   ==================================
+
+      $Id$
+
+    this tend to be outdated :-\ ...
+
+DOCS:
+=====
+
+- use case of using XInclude to load for example a description.
+  order document + product base -(XSLT)-> quote with XIncludes 
+                                                   |
+  HTML output with description of parts <---(XSLT)--
+
+TODO:
+=====
+- XInclude at the SAX level (libSRVG)
+- fix the C code prototype to bring back doc/libxml-undocumented.txt
+  to a reasonable level
+- Computation of base when HTTP redirect occurs, might affect HTTP
+  interfaces.
+- Computation of base in XInclude. Relativization of URIs.
+- listing all attributes in a node.
+- Better checking of external parsed entities TAG 1234
+- Go through erratas and do the cleanup.
+  http://www.w3.org/XML/xml-19980210-errata ... started ...
+- jamesh suggestion: SAX like functions to save a document ie. call a
+  function to open a new element with given attributes, write character
+  data, close last element, etc
+  + inversted SAX, initial patch in April 2002 archives.
+- htmlParseDoc has parameter encoding which is not used.
+  Function htmlCreateDocParserCtxt ignore it.
+- fix realloc() usage.
+- Stricten the UTF8 conformance (Martin Duerst):
+  http://www.w3.org/2001/06/utf-8-test/.
+  The bad files are in http://www.w3.org/2001/06/utf-8-wrong/.
+- xml:id normalized value
+
+TODO:
+=====
+
+- move all string manipulation functions (xmlStrdup, xmlStrlen, etc.) to
+  global.c. Bjorn noted that the following files depends on parser.o solely
+  because of these string functions: entities.o, global.o, hash.o, tree.o,
+  xmlIO.o, and xpath.o.
+
+- Optimization of tag strings allocation ?
+
+- maintain coherency of namespace when doing cut'n paste operations
+  => the functions are coded, but need testing
+
+- function to rebuild the ID table
+- functions to rebuild the DTD hash tables (after DTD changes).
+   
+
+EXTENSIONS:
+===========
+
+- Tools to produce man pages from the SGML docs.
+
+- Add Xpointer recognition/API
+
+- Add Xlink recognition/API
+  => started adding an xlink.[ch] with a unified API for XML and HTML.
+     it's crap :-(
+
+- Implement XSchemas
+  => Really need to be done <grin/>
+  - datatype are complete, but structure support is very limited.
+
+- extend the shell with:
+   - edit
+   - load/save
+   - mv (yum, yum, but it's harder because directories are ordered in
+     our case, mvup and mvdown would be required)
+
+
+Done:
+=====
+
+- Add HTML validation using the XHTML DTD
+  - problem: do we want to keep and maintain the code for handling
+    DTD/System ID cache directly in libxml ?
+  => not really done that way, but there are new APIs to check elements
+     or attributes. Otherwise XHTML validation directly ...
+
+- XML Schemas datatypes except Base64 and BinHex
+
+- Relax NG validation
+
+- XmlTextReader streaming API + validation
+
+- Add a DTD cache prefilled with xhtml DTDs and entities and a program to
+  manage them -> like the /usr/bin/install-catalog from SGML
+  right place seems $datadir/xmldtds
+  Maybe this is better left to user apps
+  => use a catalog instead , and xhtml1-dtd package
+
+- Add output to XHTML
+  => XML serializer automatically recognize the DTd and apply the specific
+     rules.
+
+- Fix output of <tst val="x&#xA;y"/>
+
+- compliance to XML-Namespace checking, see section 6 of
+  http://www.w3.org/TR/REC-xml-names/
+
+- Correct standalone checking/emitting (hard)
+  2.9 Standalone Document Declaration
+
+- Implement OASIS XML Catalog support
+  http://www.oasis-open.org/committees/entity/
+
+- Get OASIS testsuite to a more friendly result, check all the results
+  once stable. the check-xml-test-suite.py script does this
+
+- Implement XSLT
+  => libxslt
+
+- Finish XPath
+  => attributes addressing troubles
+  => defaulted attributes handling
+  => namespace axis ?
+  done as XSLT got debugged
+
+- bug reported by Michael Meallin on validation problems
+  => Actually means I need to add support (and warn) for non-deterministic
+     content model.
+- Handle undefined namespaces in entity contents better ... at least
+  issue a warning
+- DOM needs
+  int xmlPruneProp(xmlNodePtr node, xmlAtttrPtr attr);
+  => done it's actually xmlRemoveProp xmlUnsetProp xmlUnsetNsProp
+
+- HTML: handling of Script and style data elements, need special code in
+  the parser and saving functions (handling of < > " ' ...):
+  http://www.w3.org/TR/html4/types.html#type-script
+  Attributes are no problems since entities are accepted.
+- DOM needs
+  xmlAttrPtr xmlNewDocProp(xmlDocPtr doc, const xmlChar *name, const xmlChar *value)
+- problem when parsing hrefs with & with the HTML parser (IRC ac)
+- If the internal encoding is not UTF8 saving to a given encoding doesn't
+  work => fix to force UTF8 encoding ...
+  done, added documentation too
+- Add an ASCII I/O encoder (asciiToUTF8 and UTF8Toascii)
+- Issue warning when using non-absolute namespaces URI.
+- the html parser should add <head> and <body> if they don't exist
+  started, not finished.
+  Done, the automatic closing is added and 3 testcases were inserted
+- Command to force the parser to stop parsing and ignore the rest of the file.
+  xmlStopParser() should allow this, mostly untested
+- support for HTML empty attributes like <hr noshade>
+- plugged iconv() in for support of a large set of encodings.
+- xmlSwitchToEncoding() rewrite done
+- URI checkings (no fragments) rfc2396.txt
+- Added a clean mechanism for overload or added input methods:
+  xmlRegisterInputCallbacks()
+- dynamically adapt the alloc entry point to use g_alloc()/g_free()
+  if the programmer wants it: 
+    - use xmlMemSetup() to reset the routines used.
+- Check attribute normalization especially xmlGetProp()
+- Validity checking problems for NOTATIONS attributes
+- Validity checking problems for ENTITY ENTITIES attributes
+- Parsing of a well balanced chunk xmlParseBalancedChunkMemory()
+- URI module: validation, base, etc ... see uri.[ch]
+- turn tester into a generic program xmllint installed with libxml
+- extend validity checks to go through entities content instead of
+  just labelling them PCDATA
+- Save Dtds using the children list instead of dumping the tables,
+  order is preserved as well as comments and PIs
+- Wrote a notice of changes requires to go from 1.x to 2.x
+- make sure that all SAX callbacks are disabled if a WF error is detected
+- checking/handling of newline normalization
+  http://localhost/www.xml.com/axml/target.html#sec-line-ends
+- correct checking of '&' '%' on entities content.
+- checking of PE/Nesting on entities declaration
+- checking/handling of xml:space
+   - checking done.
+   - handling done, not well tested
+- Language identification code, productions [33] to [38]
+  => done, the check has been added and report WFness errors
+- Conditional sections in DTDs [61] to [65]
+  => should this crap be really implemented ???
+  => Yep OASIS testsuite uses them
+- Allow parsed entities defined in the internal subset to override
+  the ones defined in the external subset (DtD customization).
+  => This mean that the entity content should be computed only at
+     use time, i.e. keep the orig string only at parse time and expand
+     only when referenced from the external subset :-(
+     Needed for complete use of most DTD from Eve Maler
+- Add regression tests for all WFC errors
+  => did some in test/WFC
+  => added OASIS testsuite routines
+     http://xmlsoft.org/conf/result.html
+
+- I18N: http://wap.trondheim.com/vaer/index.phtml is not XML and accepted
+  by the XML parser, UTF-8 should be checked when there is no "encoding"
+  declared !
+- Support for UTF-8 and UTF-16 encoding
+  => added some convertion routines provided by Martin Durst
+     patched them, got fixes from @@@
+     I plan to keep everything internally as UTF-8 (or ISO-Latin-X)
+     this is slightly more costly but more compact, and recent processors
+     efficiency is cache related. The key for good performances is keeping
+     the data set small, so will I.
+  => the new progressive reading routines call the detection code
+     is enabled, tested the ISO->UTF-8 stuff
+- External entities loading: 
+   - allow override by client code
+   - make sure it is alled for all external entities referenced
+  Done, client code should use xmlSetExternalEntityLoader() to set
+  the default loading routine. It will be called each time an external
+  entity entity resolution is triggered.
+- maintain ID coherency when removing/changing attributes
+  The function used to deallocate attributes now check for it being an
+  ID and removes it from the table.
+- push mode parsing i.e. non-blocking state based parser
+  done, both for XML and HTML parsers. Use xmlCreatePushParserCtxt()
+  and xmlParseChunk() and html counterparts.
+  The tester program now has a --push option to select that parser 
+  front-end. Douplicated tests to use both and check results are similar.
+
+- Most of XPath, still see some troubles and occasionnal memleaks.
+- an XML shell, allowing to traverse/manipulate an XML document with
+  a shell like interface, and using XPath for the anming syntax
+  - use of readline and history added when available
+  - the shell interface has been cleanly separated and moved to debugXML.c
+- HTML parser, should be fairly stable now
+- API to search the lang of an attribute
+- Collect IDs at parsing and maintain a table. 
+   PBM: maintain the table coherency
+   PBM: how to detect ID types in absence of DtD !
+- Use it for XPath ID support
+- Add validity checking
+  Should be finished now !
+- Add regression tests with entity substitutions
+
+- External Parsed entities, either XML or external Subset [78] and [79]
+  parsing the xmllang DtD now works, so it should be sufficient for
+  most cases !
+
+- progressive reading. The entity support is a first step toward
+  asbtraction of an input stream. A large part of the context is still
+  located on the stack, moving to a state machine and putting everyting
+  in the parsing context should provide an adequate solution.
+  => Rather than progressive parsing, give more power to the SAX-like
+     interface. Currently the DOM-like representation is built but
+     => it should be possible to define that only as a set of SAX callbacks
+	and remove the tree creation from the parser code.
+	DONE
+
+- DOM support, instead of using a proprietary in memory
+  format for the document representation, the parser should
+  call a DOM API to actually build the resulting document.
+  Then the parser becomes independent of the in-memory
+  representation of the document. Even better using RPC's
+  the parser can actually build the document in another
+  program.
+  => Work started, now the internal representation is by default
+     very near a direct DOM implementation. The DOM glue is implemented
+     as a separate module. See the GNOME gdome module.
+
+- C++ support : John Ehresman <jehresma@dsg.harvard.edu>
+- Updated code to follow more recent specs, added compatibility flag
+- Better error handling, use a dedicated, overridable error
+  handling function.
+- Support for CDATA.
+- Keep track of line numbers for better error reporting.
+- Support for PI (SAX one).
+- Support for Comments (bad, should be in ASAP, they are parsed
+  but not stored), should be configurable.
+- Improve the support of entities on save (+SAX).

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+ * Consider a list L containing only namespace nodes in the

+ *    - the element E that owns the axis is in the node-set
+ *    - The nearest ancestor element of E in the node-set has a default 
+ *	    namespace node in the node-set (default namespace nodes always 
+ *      have non-empty values in XPath)
+ * The latter condition eliminates unnecessary occurrences of xmlns="" in 
+ * the canonical form since an element only receives an xmlns="" if its 
+ * default namespace is empty and if it has an immediate parent in the 
+ * canonical form that has a non-empty default namespace. To finish 
+ * processing  L, simply process every namespace node in L, except omit 
+ * namespace node with local name xml, which defines the xml prefix, 
+ * if its string value is http://www.w3.org/XML/1998/namespace.
+ *
+ * Exclusive XML Canonicalization v 1.0 (http://www.w3.org/TR/xml-exc-c14n)
+ * Canonical XML applied to a document subset requires the search of the 
+ * ancestor nodes of each orphan element node for attributes in the xml 
+ * namespace, such as xml:lang and xml:space. These are copied into the 
+ * element node except if a declaration of the same attribute is already 
+ * in the attribute axis of the element (whether or not it is included in

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+ * is followed by the progressive parser top routines, then the various
+ * high level APIs to call the parser and a few miscellaneous functions.
+ * A number of helper functions and deprecated ones have been moved to

+ * As much as possible the functions are associated with their relative
+ * production in the XML specification. A few productions defining the
+ * different ranges of character are actually implanted either in 
+ * parserInternals.h or parserInternals.c
+ * The DOM tree build is realized from the default SAX callbacks in

+ * The routines doing the validation checks are in valid.c and called either
+ * from the SAX callbacks or as standalone functions using a preparsed

+ * - other characters are processed by appending them to the normalized value 
+ * If the declared value is not CDATA, then the XML processor must further
+ * process the normalized attribute value by discarding any leading and
+ * trailing space (#x20) characters, and by replacing sequences of space
+ * (#x20) characters by a single space (#x20) character.

+# This is a "Work in Progress" attempt at a python script to run the
+# various regression tests.  The rationale for this is that it should be
+# possible to run this on most major platforms, including those (such as
+# Windows) which don't support gnu Make.
+#
+# The script is driven by a parameter file which defines the various tests
+# to be run, together with the unique settings for each of these tests.  A
+# script for Linux is included (regressions.xml), with comments indicating
+# the significance of the various parameters.  To run the tests under Windows,
+# edit regressions.xml and remove the comment around the default parameter
+# "<execpath>" (i.e. make it point to the location of the binary executables).
+#
+# Note that this current version requires the Python bindings for libxml2 to
+# have been previously installed and accessible
+#
+# See Copyright for the status of this software.

+# Take a look at the beginning and modify the variables to suit your 
+# environment. Having done that, you can do a
+#
+# nmake [all]     to build the libxml and the accompanying utilities.
+# nmake clean     to remove all compiler output files and return to a
+#                 clean state.
+# nmake rebuild   to rebuild everything from scratch. This basically does
+#                 a 'nmake clean' and then a 'nmake all'.
+# nmake install   to install the library and its header files.

+# Take a look at the beginning and modify the variables to suit your

+# make [all]     to build the libxml and the accompanying utilities.

+# make install   to install the library and its header files.

+# Makefile for libxml2, specific for Windows, MSVC and NMAKE.

+# Take a look at the beginning and modify the variables to suit your 
+# environment. Having done that, you can do a
+#
+# nmake [all]     to build the libxml and the accompanying utilities.
+# nmake clean     to remove all compiler output files and return to a
+#                 clean state.
+# nmake rebuild   to rebuild everything from scratch. This basically does
+#                 a 'nmake clean' and then a 'nmake all'.
+# nmake install   to install the library and its header files.

+
+
+
+1. General
+==========
+
+
+1.1 Building From The Command-Line
+----------------------------------
+
+This is the easiest, preferred and currently supported method. It can
+be that a subdirectory of the directory where this file resides 
+contains project files for some IDE. If you want to use that, please
+refer to the readme file within that subdirectory.
+
+In order to build from the command-line you need to make sure that
+your compiler works from the command line. This is not always the
+case, often the required environment variables are missing. If you are
+not sure, test if this works first. If it doesn't, you will first have
+to configure your compiler suite to run from the command-line - please
+refer to your compiler's documentation regarding that.
+
+The first thing you want to do is configure the source. You can have
+the configuration script do this automatically for you. The
+configuration script is written in JScript, a Microsoft's
+implementation of the ECMA scripting language. Almost every Windows
+machine can execute this through the Windows Scripting Host. If your
+system lacks the ability to execute JScript for some reason, you must
+perform the configuration manually and you are on your own with that.
+
+The second step is compiling the source and, optionally, installing it
+to the location of your choosing.
+
+
+1.2 Configuring The Source
+--------------------------
+
+The configuration script accepts numerous options. Some of these
+affect features which will be available in the compiled software,
+others affect the way the software is built and installed. To see a
+full list of options supported by the configuration script, run
+
+  cscript configure.js help
+
+from the win32 subdirectory. The configuration script will present you
+the options it accepts and give a biref explanation of these. In every
+case you will have two sets of options. The first set is specific to
+the software you are building and the second one is specific to the
+Windows port.
+
+Once you have decided which options suit you, run the script with that
+options. Here is an example:
+
+  cscript configure.js compiler=msvc prefix=c:\opt 
+    include=c:\opt\include lib=c:\opt\lib debug=yes
+
+The previous example will configure the process to use the Microsoft's
+compiler, install the library in c:\opt, use c:\opt\include and 
+c:\opt\lib as additional search paths for the compiler and the linker 
+and build executables with debug symbols.
+
+Note: Please do not use path names which contain spaces. This will
+fail. Allowing this would require me to put almost everything in the
+Makefile in quotas and that looks quite ugly with my
+syntax-highlighting engine. If you absolutely must use spaces in paths
+send me an email and tell me why. If there are enough of you out there
+who need this, or if a single one has a very good reason, I will
+modify the Makefile to allow spaces in paths.
+
+
+1.3 Compiling
+-------------
+
+After the configuration stage has been completed, you want to build
+the software. You will have to use the make tool which comes with
+your compiler. If you, for example, configured the source to build
+with Microsoft's MSVC compiler, you would use the NMAKE utility. If
+you configured it to build with GNU C compiler, mingw edition, you
+would use the GNU make. Assuming you use MSVC, type
+
+  nmake /f Makefile.msvc
+
+and if you use MinGW, you would type
+
+  make -f Makefile.mingw
+
+and if you use Borland's compiler, you would type
+
+  bmake -f Makefile.bcb
+
+in the win32 subdirectory. When the building completes, you will find
+the executable files in win32\bin.* directory, where * stands for the
+name of the compiler you have used.
+
+
+1.4 Installing
+--------------
+
+You can install the software into the directory you specified to the
+configure script during the configure stage by typing (with MSVC in
+this example)
+
+  nmake /f Makefile.msvc install
+
+That would be it, enjoy.
+
+
+
+
+
+2. Compiler Specifics
+=====================
+
+
+2.1 Microsoft Visual C/C++
+--------------------------
+
+If you use the compiler which comes with Visual Studio .NET, note that
+it will link to its own C-runtime named msvcr70.dll or msvcr71.dll. This 
+file is not available on any machine which doesn't have Visual Studio 
+.NET installed.
+
+
+2.2 GNU C/C++, Mingw edition
+----------------------------
+
+When specifying paths to configure.js, please use slashes instead of 
+backslashes for directory separation. Sometimes Mingw needs this. If
+this is the case, and you specify backslashes, then the compiler will 
+complain about not finding necessary header files.
+
+
+2.2 Borland C++ Builder
+-----------------------
+
+To compile libxml2 with the BCB6 compiler and associated tools, just follow
+the basic instructions found in this file file. Be sure to specify 
+the "compiler=bcb" option when running the configure script. To compile the
+library and test programs, just type
+
+  make -fMakefile.bcb
+
+That should be all that's required. But there are a few other things to note:
+
+2.2.1 Building with iconv support
+
+If you configure libxml2 to include iconv support, you will obviously need to
+obtain the iconv library and include files. To get them, just follow the links 
+at http://www.gnu.org/software/libiconv/ - there are pre-compiled Win32 
+versions available, but note that these where built with MSVC. Hence the 
+supplied import library is in COFF format rather than OMF format. You can 
+convert this library by using Borland's COFF2OMF utility, or use IMPLIB to 
+build a new import library from the DLL. Alternatively, it is possible to
+obtain the iconv source, and build the DLL using the Borland compiler.
+
+There is a minor problem with the header files for iconv - they expect a
+macro named "EILSEQ" in errno.h, but this is not defined in the Borland
+headers, and its absence can cause problems. To circumvent this problem, I
+define EILSEQ=2 in Makefile.bcb. The value "2" is the value for ENOFILE (file
+not found). This should not have any disastrous side effects beyond possibly
+displaying a misleading error message in certain situations.
+
+2.2.2 Compatability problems with MSVC (and probably CYGWIN)
+
+A libxml2 DLL generated by BCB is callable from MSVC programs, but there is a
+minor problem with the names of the symbols exported from the library. The
+Borland compiler, by default, prepends an underscore character to global 
+identifiers (functions and global variables) when generating object files.
+Hence the function "xmlAddChild" is added to the DLL with the name
+"_xmlAddChild". The MSVC compiler does not have this behaviour, and looks for
+the unadorned name. I currently circumvent this problem by writing a .def file
+which causes BOTH the adorned and unadorned names to be exported from the DLL.
+This behaviour may not be supported in the future.
+
+An even worse problem is that of generating an import library for the DLL. The
+Borland-generated DLL is in OMF format. MSVC expects libraries in COFF format,
+but they don't provide a "OMF2COFF" utility, or even the equivalent of
+Borland's IMPLIB utility. But it is possible to create an import lib from the
+.def file, using the command:
+  LIB /DEF:libxml2.def
+
+If you don't have the .def file, it's possible to create one manually. Use
+DUMPBIN /EXPORTS /OUT:libxml2.tmp libxml2.dll to get a list of the exported
+names, and edit this into .def file format.
+
+A similar problem is likely with Cygwin.
+
+2.2.3 Other caveats
+
+We have tested this only with BCB6, Professional Edition, and BCB 5.5 free
+command-line tools.

+<!-- 
+	win32/defgen.xsl
+	This stylesheet is used to transform doc/libxml2-api.xml into a pseudo-source,
+	which can then be preprocessed to get the .DEF file for the Microsoft's linker.
+	
+	Use any XSLT processor to produce a file called libxml2.def.src in the win32
+	subdirectory, for example, run xsltproc from the win32 subdirectory:
+	
+	  xsltproc -o libxml2.def.src defgen.xsl ../doc/libxml2-api.xml
+	  
+	Once that finishes, rest assured, the Makefile will know what to do with the
+	generated file.

+.TH GNOME-XML 1 "3 July 1999" Version 1.1.0
+.SH NAME
+xml-config - script to get information about the installed version of GNOME-XML
+.SH SYNOPSIS
+.B xml-config
+[\-\-prefix\fI[=DIR]\fP] [\-\-libs] [\-\-cflags] [\-\-version] [\-\-help]
+.SH DESCRIPTION
+\fIxml-config\fP is a tool that is used to determine the compile and
+linker flags that should be used to compile and link programs that use
+\fIGNOME-XML\fP.
+.SH OPTIONS
+.l
+\fIxml-config\fP accepts the following options:
+.TP 8
+.B  \-\-version
+Print the currently installed version of \fIGNOME-XML\fP on the standard output.
+.TP 8
+.B  \-\-libs
+Print the linker flags that are necessary to link a \fIGNOME-XML\fP program.
+.TP 8
+.B  \-\-cflags
+Print the compiler flags that are necessary to compile a \fIGNOME-XML\fP program.
+.TP 8
+.B  \-\-prefix=PREFIX
+If specified, use PREFIX instead of the installation prefix that
+\fIGNOME-XML\fP was built with when computing the output for the
+\-\-cflags and \-\-libs options. This option must be specified before
+any \-\-libs or \-\-cflags options.
+.SH AUTHOR
+This manual page was written by Fredrik Hallenberg <hallon@lysator.liu.se>,
+for the Debian GNU/linux system (but may be used by others).

+/**
+ * xmlXPathEscapeUriFunction:
+ * @ctxt:  the XPath Parser context
+ * @nargs:  the number of arguments
+ *
+ * Implement the escape-uri() XPath function
+ *    string escape-uri(string $str, bool $escape-reserved)
+ *
+ * This function applies the URI escaping rules defined in section 2 of [RFC
+ * 2396] to the string supplied as $uri-part, which typically represents all
+ * or part of a URI. The effect of the function is to replace any special
+ * character in the string by an escape sequence of the form %xx%yy...,
+ * where xxyy... is the hexadecimal representation of the octets used to
+ * represent the character in UTF-8.
+ *
+ * The set of characters that are escaped depends on the setting of the
+ * boolean argument $escape-reserved.
+ *
+ * If $escape-reserved is true, all characters are escaped other than lower
+ * case letters a-z, upper case letters A-Z, digits 0-9, and the characters
+ * referred to in [RFC 2396] as "marks": specifically, "-" | "_" | "." | "!"
+ * | "~" | "*" | "'" | "(" | ")". The "%" character itself is escaped only
+ * if it is not followed by two hexadecimal digits (that is, 0-9, a-f, and
+ * A-F).
+ *
+ * If $escape-reserved is false, the behavior differs in that characters
+ * referred to in [RFC 2396] as reserved characters are not escaped. These
+ * characters are ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | ",".
+ *
+ * [RFC 2396] does not define whether escaped URIs should use lower case or
+ * upper case for hexadecimal digits. To ensure that escaped URIs can be
+ * compared using string comparison functions, this function must always use
+ * the upper-case letters A-F.
+ *
+ * Generally, $escape-reserved should be set to true when escaping a string
+ * that is to form a single part of a URI, and to false when escaping an
+ * entire URI or URI reference.
+ *
+ * In the case of non-ascii characters, the string is encoded according to
+ * utf-8 and then converted according to RFC 2396.
+ *
+ * Examples
+ *  xf:escape-uri ("gopher://spinaltap.micro.umn.edu/00/Weather/California/Los%20Angeles#ocean"), true())
+ *  returns "gopher%3A%2F%2Fspinaltap.micro.umn.edu%2F00%2FWeather%2FCalifornia%2FLos%20Angeles%23ocean"
+ *  xf:escape-uri ("gopher://spinaltap.micro.umn.edu/00/Weather/California/Los%20Angeles#ocean"), false())
+ *  returns "gopher://spinaltap.micro.umn.edu/00/Weather/California/Los%20Angeles%23ocean"

+ * Function implementing the string-range() function
+ * range as described in 5.4.2 
+ *
+ * ------------------------------
+ * [Definition: For each location in the location-set argument,
+ * string-range returns a set of string ranges, a set of substrings in a
+ * string. Specifically, the string-value of the location is searched for
+ * substrings that match the string argument, and the resulting location-set
+ * will contain a range location for each non-overlapping match.]
+ * An empty string is considered to match before each character of the
+ * string-value and after the final character. Whitespace in a string
+ * is matched literally, with no normalization except that provided by
+ * XML for line ends. The third argument gives the position of the first
+ * character to be in the resulting range, relative to the start of the
+ * match. The default value is 1, which makes the range start immediately
+ * before the first character of the matched string. The fourth argument
+ * gives the number of characters in the range; the default is that the
+ * range extends to the end of the matched string.
+ *
+ * Element boundaries, as well as entire embedded nodes such as processing
+ * instructions and comments, are ignored as defined in [XPath].
+ *
+ * If the string in the second argument is not found in the string-value
+ * of the location, or if a value in the third or fourth argument indicates
+ * a string that is beyond the beginning or end of the document, the
+ * expression fails.
+ *
+ * The points of the range-locations in the returned location-set will
+ * all be character points.
