It seems to me that the explicit agreements will be based on a common
registry/repository facility that all parties agree to use during the 
interchange, regardless whether it is a formalism based ISO or W3C or 
else.  (Besides, as I understand TM template is by definition a TM 
also.)  For example, I can anticipate the common registry/repository 
will be used for all kinds of metadata (in the generic sense), 
including XML Namespace, DTD, XML Schema, RDF, Topic Maps, 
Architecture Forms, etc.

I do not know what RELAX is, but based on my comments above I don't 
think the common registry/repository has to be limited to contain DTD 
syntax only.
