There is an implicit assumptions in your comments that I'd challenge. 
You seem to be focusing on using schemas to validate *documents* as 
opposed to *elements*. If we refocus on elements rather than 
documents, the question is a lot easier to answer. Each element has a 
unique namespace. If that namespace has a RDDL document, then we can 
query that document to find a schema appropriate for validating that 
element.

As per language, whichever one you want to use. If you like RELAX, 
use RELAX. If you like the W3C XML Schema Language, use that. 
However, if there are more than one in a given language then dispatch 
based on the purpose rather than the nature.
