I've updated the various extension drafts to point to RFC4287.
The feed thread draft is a major update that includes a simplification
of the in-reply-to element.
<in-reply-to
id="tag:example.org,2005:some-unique-id"
href="http://example.com/some-location" />
I'm moving the feed rank draft the "stable" status.. meaning that
changes are unlikely between now and when I submit the draft as a
standards-track RFC (which will be after APP is complete).
There is a new draft that defines a "transitional atom" format. The
t-atom format is usable during the production lifecycle of Atom entries;
as such certain requirements from core Atom are relaxed (e.g. atom:id is
optional, etc).
Works in progress:
