milestones (Revised WG Charter Proposal)

At this point, "revising" and "WG last call" milestones seem
quite pointless and meaningless to me (because they can be
declared "Done" without actually making any forward progress).

We need "we think we're done" milestones.  I strongly suggest
that for each I-D we include a milestone of the form:

DATE	Progress FOO I-D to the IESG for consideration as a
	BAR RFC

where DATE is the date which this WG commits to completing
its work on the I-D (excepting post-IESG-progression work),
FOO is the name of the I-D, and BAR is indicative of the
track which the I-D is to be considered for.
