The problem with this is that it is incompatible with XML Schema's notion of named types and type derivation which unfortunately it seems the W3C XML Query working group is refusing to accept given the last draft of the XQuery formal semantics I laid my eyes on. > Could you elaborate? Is the XQuery WG really re-thinking WXSDL named types in favor of a more XDuce/RELAX NG-like pattern-based approach? I think I mis-parsed something, or maybe your sense of "unfortunately" is not the same as mine :~)
