Regular Expressions : \w incorrectly matching punctuation characters

           Summary: Regular Expressions : \w incorrectly matching
                    punctuation characters
           Product: Xerces-C++
           Version: 1.7.0
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Validating Parser (Schema) (Xerces 1.5 or up only)
        AssignedTo: xerces-c-dev@xml.apache.org
        ReportedBy: richard_schofield@uk.ibm.com


The XML Schema Spec Part 2 (Appendix F) defines the multi-charcater escapes 
which can be used in regular expression matching.

\w should match all characters EXCEPT the set of "punctuation", "separator" 
and "other" characters as defined by the unicode specification.

However, \w sets up a range which matches all characters between x0020 and 
xD7FF (gXMLChars). This range results in the punctuation, separator and other 
characters being matched incorrectly.
