Hi Deepak,

Are you planning on publishing an updated draft today?
I'd like to move the draft ahead to IESG Evaluation.

Thanks,
Alia

I've added Tissa to the cc list above. I believe that for now he wants
to be listed with "Consultant" as his affiliation and with email
address <tsenevir@gmail.com<mailto:tsenevir@gmail.com>>.

The IETF LC ends the 13th, in a few days. I suggest that you update
the contact info for Tissa, spell out OAM, and update the
MODULE-IDENTITY, since those don't seem like they would be
controversial. For any changes to the Security Considerations text, I
suggest you post proposed text in this thread before editing it in.

Thanks,
Donald (Shepherd)
