I disagree ... I thought we were looking for namespace-based mechanisms for
adding information to an instance keeping entirely within the XML Infoset.

I don't think we have reached such a conclusion yet.

I didn't think we were doing *any* syntax changing (except the retrofit of
SGML for namespaces if that ended up being assessed as feasible, which I'm
not convinced of yet) ... I thought our work was entirely based on the
Infoset ... XML in and XML out with augmented information maintained using
existing information set facilities.
