You've lost me here.  All I was suggesting is that, for a given document,
the primary vocabulary (the one that's associated to the doctype) should
never be namespaced.  I see no point in namespacing it.  Regardless of
whether other vocabularies are mixed into the same document, no namespace is
needed for the primary vocabulary (while all other vocabularies must be
namespaced).  If that same vocabulary is used in another document not as the
primary vocabulary, then it would be namespaced.  I certainly don't see a
need to change element names (any more than the colonified name hack does).
Why would this approach be problematic?  What am I missing?
