RE: [xml-dev] The <any/> element: bane of security or savior ofversioning?

Oh that is great! Thanks, we missed that.

By the way, I think the XSLT2 conformance is wrong if it doesn't include
the built-in derived types. Users often don't understand the type
hierarchy, and it promotes the nominal hierarchy of the built-in types
into being something real whereas it is just a theoretical artifact and
something to help implementors.
