[PATCH] Warning when old/unexpected schema-instance ref detected.

[Wayne Bradney]

This has been the cause of a lot of confusion when validating old documents
with newer versions of Xerces.
Standard error messages make it seem like the document is invalid -- this
will just add a WARNING message up-front.
[The attached patch is based on the "src" release of Xerces-1.4.0, since I
don't have access to CVS through my company's firewall.]
