This is a known bug in Xerces-C++ that was fixed for the next version:

http://issues.apache.org/jira/browse/XERCESC-1517

I see two ways to address this:

1. Apply the fix to Xerces-C++ 2.7.0. Let me know if you need help
   extracting the patch (I have the SVN tree checked out).

2. If (1) is not acceptable, then you can change elements.txx in
   libxsd/xsd/cxx/xml/dom to call

   parser->setFeature(XMLUni::fgXercesDOMHasPSVIInfo, true)

   There are two places: around line 352 and 478. This will work
   because XSD does not make a copy of the DOM documents that it
   creates internally.
