Summary: Ready with a minor issue

Major issues: none

Minor issues:

This is the same version I reviewed at LC. After discussion with the
authors I have changed my question to a recommendation.

In 6.1.2 and 6.1.3 it says: "If the answerer rejects the offer because the
available reference clocks are incompatible, the rejection MUST
contain at least one timestamp reference clock specification usable by
the answerer."  I have learned that sending this reference clock
specification is not required for the protocol to function. It is for
the offerer's information, so that maybe next time the negotiation
will succeed.

- Since including the reference clock is not required for the protocol
per se to work, consider making this MUST a SHOULD.

- In any case, this needs to be justified. Even something as simple as
adding "for the offerer's information" could be sufficient, although
usually more would be expected.
