I think there's just one fundamental disagreement here, so I'll respond
to that first.  After that, just a couple of quickies.

Hmm, that wouldn't be my preference.  My preference would be that it is
possible for there to be a mismatch between a set of features/MEPs,
and a protocol binding.  i.e. "sorry, there's no reasonable way to
implement this feature/MEP with this underlying protocol"

Perhaps because it wants to account for SOAP.

Well, I didn't say the body would have to contribute to identifying
anything.  It could just be an alternate header syntax[1].  8-O
