Paul, you're about the fifth smart person to fall into this trip which 
means it's a nasty one and RDDLers have to be careful.  There's no such 
thing as a RDDL for a document.  There's a RDDL for a *namespace*.

The problems of multi-namespace docs, and whether there is such a thing 
as a good general best practice for how to process them, is a big ugly 
problem that hasn't received enough consideration.  RDDL might be a 
little piece of the solution (at least there's a place to go when 
information-gathering about any one of the namespaces) but there's way 
more to it.  At the moment I'm unconvinceed there's a useful general 
solution.

And by the way this is another gold star for XML-dev, where the RDDL 
ideas emerged & got worked out back in late 2000.  -Tim
