Actually I'm not convinced that the RDDL specification is technically 
limited that way**, but I understand that namespace explanation is the 
central point of RDDL. Let me rephrase my point:

  * if I encounter a document "out of the blue" with only one namespace, 
I would confidently look up the RDDL and use the schemas, stylesheets, 
classes, etc. specified there.

  * if I encounter a document o-o-t-b with only one namespace 
represented on the root element, but others inline, I would proceed to 
the RDDL with about 80% certainty (not sure what to do in code about 
this confusion, but...). I would have NO IDEA what to do about the 
schemas, etc. for the inner namespaces.

  * if I encounter a document o-o-t-b with a namespace on the root and 
another namespace on an attribute then my certainty about the 
applicability of the RDDL has to drop to about 60% because of the XSLT 

I find this personally an uncomfortable situation but I think that RDDL 
only exposes it, not causes it.

** on thinking about it, I kind of wonder whether documents should be 
able to suggest RDDLs as they can suggest schemas and stylesheets.
