I had suggested using some other term than "requirements", because the
liaison to the IETF came from SA2 (architecture) in 3GPP, not SA1
(requirements), and I'm concerned about this turning into a three-ring
circus between SA2, SA1, and SA plenary (all of which communicate with each
other through formal liaison statements approved at formal meetings).

Perhaps I worry too much. Do the right thing, of course.

The rest of this response seems fine. Thanks for the quick reaction.
