XMLSpy">XMLSpy has their own XML Schema validator that in my experience has a lot 
of areas where it is not conformant with the standard.

I would trust MSXML, Xerces or Saxon as validators, and just use XMLSpy">XMLSpy for 
editing.

If you really want it to validate in XMLSpy">XMLSpy, I would suggest using the 
union type example from my previous mail - that should work.

Hope that helps,
Priscilla
