I don't see why you think it doesn't, but it may be because of the
misunderstandings that I correct in my responses below.

None of these are necessary.

There's no need to distinguish.  Handling of required fields being
missing won't be needed if the client supports enforcement, so the
server just needs to redisplay the form with a note about the
requirement, as servers do today.  Handling of the submission of a WF2
repetition input won't be needed if the client supports the WF2
repetition model, so a server receiving such a submission just needs to
generate the repetition manually for the old client.

Again, unnecessary.  The point is that the WF2 syntax can be sent to
existing clients.

Likewise, unnecessary.

That solution is possible and probably often necessary for XForms, but
WF2 is designed so that it is unnecessary.
