If you read the release notes for XMLSpy Beta 3, you'll find...

" + the following XML Schema components are not yet implemented inside the
validator core:
        - all
        - anyAttribute
        - unique, key, keyref
        - redefine
        - final
        - use=prohibited
        - abstract, block, nullable
        - user-defined duration and period facets (the built-in types are,
however, fully supported)
        - \p{X} category escape for pattern facets
        - \p{IsX} block escape for pattern facets
"

I have had the same problem with abstract types, have emailed XMLSpy, and
have received an assurance
that support will be there in the production version. It would be nice to
see it sooner rather than later though :-)

Hope this helps.

Regards
Michael

I believe your stuff is OK, so I guess we need to here from XML Spy as
to why they reject it.
