No, it can be used for this provided each element is in a namespace,
each such namespace URI has a RDDL document including a link to a
relevant schema, and the schema language and the schemas themselves
are designed to allow these sorts of multiple namespace documents.
(The last point is the biggest obstacle in practice.)

Yes, absolutely.

Maybe I understand it, but I disagree with it. RDDL is good at what
it does, and useful. It is not a bad thing. If you want do something
else useful that's orthogonal to RDDL, that's fine; but this in no
way indicates that RDDL should not be used or supported. What you're
proposing does not go further. It goes in a different direction.
