Hi all,

Thanks for the updates; they look good!

Before I kick off the IETF LC, I just have two things I wanted to
double-check (we may not need a new rev before the LC):

(1) In Section 3.2 (Representation of an Asymmetric Proof-of-Possession
Key), the last paragraph is a somewhat different from the main content, in
that it mentions using "COSE_Key" for an encrypted symmetric key, analogous
to the last paragraph of Section 3.2 of RFC 7800.  I had wanted to see some
additional discussion, but we agreed that this was analogous to RFC 7800
and we did not need to go "out of parity" with it on this point.  So we
should be able to go ahead without new text here, but did we want to
explicitly refer back to that portion of RFC 7800 to make the connection
clear?

(2) In https://github.com/cwt-cnf/i-d/pull/27/files we removed a large
chunk of text since it contained several things that are inaccurate.  The
only things that were removed that I wanted to check if we should think
about keeping was the note that the same key might be referred to by
different key IDs in messages directed to different recipients.  What do
people think about that?

Thanks,

Ben
