In answering, I take all instances of "supercede" and "extend" and 
replace them with "serve as next the next generation of".  Answer: yes.

No and yes.  RDF is meant for metadata interchange.  DCD is a next-gen
DTD proposal based in part on the premise that it's useful to think of
schemas as metadata, and hence to use RDF to interchange them.

Well, you left out DDML AKA XSchema.  It is fair to say that these
proposals rush madly off in all directions.  Further explication requires
understanding details and players.  But don't bother.  It is to be hoped 
that the W3C "XML Schema Working Group" process will digest this input and 
produce something usable before it's too late. -Tim
