Thanks Randy. I think this is ready for last call now. I have a couple of comments below that can be resolved together with last call comments. > On Dec 15, 2016, at 7:17 PM, Randall Gellens <rg+ietf@randy.pensive.org> wrote: > >> = Section 10.1 = >> >> I don't understand why support for messages would be assumed to be >> cumulative in the order in which messages end up being registered >> in the registry.

I guess when I read “We will help you as soon as possible” that sounds to me like it could be a long time from now, which is different from “Help is on the way.” But I see how others might interpret the first one differently.
