RE: How to Version XML Applications

Isn't that going to lead back to the potential of 
having a document with multiple namespaces but no 
normative schema?  That's a can of worms.  It is as if one 
wanted versioning for relational views when in effect,
one should version the query that creates them.

You force the document to be self describing by adding a required
version attribute or element. If the attribute is present, you know
the version. If it's missing, the document isn't valid according to
its schema.
