Hi Maria,

We've started the discussion on Intended Status,
so I'll start with the quicker questions and comments
on initial-registry draft below.

I think Michelle and I were more comfortable that the 
each section/template indicated exactly where IANA assignments
were needed. It's the line between the shared responsibility of Expert 
Review and IANA to create a complete entry in the registry.

Yes, this column is something IANA/Michelle asked for, and I think we 
could be convinced that IESG could replace IETF. But to me, 
"Standards Action" is IETF.

The reason is simple, a draft may specify more than one registry entry,
as -initial-registry does.

I left the secY part general in case of changes during review.
It's very easy to fill this field at the end, when there is no 
possible shuffling of section order that then requires name edits,

Yes, I need to use a text editor and globally update to 7679 and 7680,
XMLMind doesn't seem to let me search in the reference fields easily
(when viewing the XML source).
