Agreed.

Agreed again. Do you agree that it makes more sense to associate
schemas, stylesheets, etc. with document types than with namespaces?

A simple PI.

Right, and RDDL might be an appropriate target language for that.

That's mostly true. But the thing that has Nicolas and Paul so excited
is that of the two choices (namespace and doctypes), we've developed an
infrastructure for associating schemas and stylesheets with the wrong
thing. The actual file format may be appropriate for doing the other
task but we just need to declare that best practice is now to associate
RDDL's with schemas and namespaces to document types, not namespaces.
