+ *
+ * Revision 18: October 27, 2005
+ * DOM 3 XPath support. Caveats:
+ * - namespace prefixes aren't resolved in XPathEvaluator.createExpression,
+ * but in XPathExpression.evaluate.
+ * - XPathResult.invalidIteratorState is not implemented.
+ *
+ * Revision 17: October 25, 2005
+ * Some core XPath function fixes and a patch to avoid crashing certain
+ * versions of MSXML in PathExpr.prototype.getOwnerElement, thanks to
+ * Sébastien Cramatte <contact (at) zeninteractif.com>.
+ *
+ * Revision 16: September 22, 2005
+ * Workarounds for some IE 5.5 deficiencies.
+ * Fixed problem with prefix node tests on attribute nodes.
+ *
+ * Revision 15: May 21, 2005
+ * Fixed problem with QName node tests on elements with an xmlns="...".
+ *
+ * Revision 14: May 19, 2005
+ * Fixed QName node tests on attribute node regression.
+ *
+ * Revision 13: May 3, 2005
+ * Node tests are case insensitive now if working in an HTML DOM.
+ *
+ * Revision 12: April 26, 2005
+ * Updated licence. Slight code changes to enable use of Dean
+ * Edwards' script compression, http://dean.edwards.name/packer/ .
+ *
+ * Revision 11: April 23, 2005
+ * Fixed bug with 'and' and 'or' operators, fix thanks to
+ * Sandy McArthur <sandy (at) mcarthur.org>.
+ *
+ * Revision 10: April 15, 2005
+ * Added support for a virtual root node, supposedly helpful for
+ * implementing XForms. Fixed problem with QName node tests and
+ * the parent axis.
+ *
+ * Revision 9: March 17, 2005
+ * Namespace resolver tweaked so using the document node as the context
+ * for namespace lookups is equivalent to using the document element.
+ *
+ * Revision 8: February 13, 2005
+ * Handle implicit declaration of 'xmlns' namespace prefix.
+ * Fixed bug when comparing nodesets.
+ * Instance data can now be associated with a FunctionResolver, and
+ * workaround for MSXML not supporting 'localName' and 'getElementById',
+ * thanks to Grant Gongaware.
+ * Fix a few problems when the context node is the root node.
+ *
+ * Revision 7: February 11, 2005
+ * Default namespace resolver fix from Grant Gongaware
+ * <grant (at) gongaware.com>.
+ *
+ * Revision 6: February 10, 2005
+ * Fixed bug in 'number' function.
+ *
+ * Revision 5: February 9, 2005
+ * Fixed bug where text nodes not getting converted to string values.
+ *
+ * Revision 4: January 21, 2005
+ * Bug in 'name' function, fix thanks to Bill Edney.
+ * Fixed incorrect processing of namespace nodes.
+ * Fixed NamespaceResolver to resolve 'xml' namespace.
+ * Implemented union '|' operator.
+ *
+ * Revision 3: January 14, 2005
+ * Fixed bug with nodeset comparisons, bug lexing < and >.
+ *
+ * Revision 2: October 26, 2004
+ * QName node test namespace handling fixed. Few other bug fixes.
+ *
+ * Revision 1: August 13, 2004
+ * Bug fixes from William J. Edney <bedney (at) technicalpursuit.com>.
+ * Added minimal licence.
+ *
+ * Initial version: June 14, 2004
