I don't think that it's useless, and I can see many useful usages of
schemas including for modeling purposes.

My point was rather to warn against the danger of a transfer of
"semantic" (or "meaning") between instance documents and schemas.

IMHO, we should keep as much semantic as possible in the instance
documents ;) ...

Otherwise, my library could become:

<a001 xmlns="http://example.org/ns/books">

plus a schema that explains what the elements are meaning...

Yes, these features are opening a wide scope of applications. 

That doesn't mean a single tool and language should try to cover all the
scope though and I think extension frameworks (such as SAF) have also a
role to play.
