Architectural forms can do everything that namespaces do, but not in
such a web-friendly way.  Namespaces can handle only a small subset of 
what architectural forms can do.

The AF equivalent of a qualified name is the URL or public ID of the
meta-DTD file combined with the architectural form.  It hasn't really
taken off, though, and I agree that self-identifying AFs
(i.e. qualified names) show some promise.

All the best,
