Before you go on saying what can be fixed and what not can be fixed in the
current draft I think it would be instructive to point out that you have
yet to identify a correctness problem in the *current*design* based on what
is *supported* by the specification.

As far as I can tell, you have until now shown what will break *if* the
design was different in that a proxy could pick what it wanted to comply
with and forward the rest. This is *not* a part of the current design nor
do I believe this is in any way implied by the specification asis (in fact
I have shown you at least one scenario where this does not work).

Please be aware that if are proposing a *different* design than what is
currently described then that is fine but let's try and keep things separate.
