This version of the draft closes almost all open issues that
were
discussed during last meeting. See "Changes since
-03" section (I forgot
to remove the open issues section). We have a little over
two-and-half
weeks before we can do another submission for IETF 68. That
depends on
good review comments from somebody. I will try to read it
over again
before that time. Please read the draft and send me
comments.
