No, no particular reason. Except... hmm... it was
discussed briefly with a few folks, and I took
away from that discussion that no, these could
wait for a future version or a layer on top or something.

Would anybody else care to second this request for
enhancement? Any particular practical motivation?
Anybody have tools that could exploit them,
or tools that suffer for the lack of them, or
ontologies that you're building that are particularly
awkward without them?

Better yet: how about writing a schema/ontology for these
and putting it in the Web, showing how it works, and
seeing if anybody else finds it useful?

Yes, we could.
