Summary: Almost Ready

Major Concerns:

This document, once approved, will update RFC 5661 and RFC 7862.  It
seems to me that it should also update RFC 7530.  It fulfills a promise
made in Section 11 of RFC 7530.

Minor Concerns:

In Section 4.2, the last bullet in the section is unusual.  That bullet
add a new context for the entire list of bullets.  It would be better
for the introduction to the list to provide the full context at the
beginning.

Nits:

Throughout the document, some bullet items end with periods and others
do not.  Use of the period is more common.  Please pick one style and
use it throughout the document.

The last sentence of the Introduction is not clear.  After reading it
several times, I think you are trying to say:

   ... enabling interoperation to proceed just as if both
   implementations supported only the parts of the protocol
   that are being used.

In Section 2.3:
s/(not necessarily proper)/(not necessarily a proper subset)/

In Section 4.4.2, in the last set of bullets, the first bullet begins
with "The minor version consists", but it should begin with "When the
minor version consists".  The "so" following the comma should also be
removed.

In Section 6, 2nd paragraph, I found the text confusing because
"following" is used with two very different meanings in the same
sentence.  I suggest: S/to following/to obeying/
