    Summary: XInclude bug on included xml that its own schema and no DTD
       Type: Bug

     Status: Open
   Priority: Blocker

    Project: Xerces2-J

             XInclude 1.0
   Versions:

Description:
I get the following error message under both the 2.5.0 and 2.6.0 releases using
XInclude. The included file (pmtext) has its own schema in its own namespace but
no DTD. The including file also has its own schema and no DTD. The including
file's schema imports the included file's schema.

==================


I ran it under a debugger and the messages are generated in
XMLNSDocumentScannerImpl.scanStartElement() at the start of the included file.
fPerformValidation is false for the including document but becomes true for the
included document. My guess is that somehow the DTD validator is turned back on.

Under 2.5.0, I simply commented out the fPerformValidation check and everything
worked correctly. However, under 2.6.0 I get a null pointer exception at the
following because parentBaseURI is null:

ava.lang.NullPointerException
