Thanks for the reference.

It seems, Xerces-J' s XSD 1.1 implementation is also on the way.

I also feel, number of complete implementations of a spec is not the
only measure of usefulness of any language. The language being much
complex and providing lot of functionality, in fact I think raises the
bar on quality and skills of implementers.

I am just one of the persons, who has contributed somewhat to Xerces-J
XSD 1.1 implementation. It's not fair to say, that Xerces is mine :(
But I like Xerces very much.

I am really not sure, why entities are not allowed to be defined in
XSD. I believe, there is some design principle behind that, and also
the XML Schema WG must be aware about this issue I believe.
