There are some acronyms that could usefully be expanded on first use.

Section 3.1

TMOD extension parameter

It is unusual to allocate whole 32bit words of reserved space for
future use. We normally leave out this sort of padding in the knowledge
that we can always extend objects in the future.

Section 4.1

   QNEs may be Stateful in some limited aspects, but obviously it is
   preferable to deploy stateless QNEs.

This seems a bit unhelpful.

If it needs to be said, it is not "obvious". So you should explain your
assertion with a bried reason.

"...in some limited aspects" is not very clear. What does it mean?

Editorial nit: IN section 2.1, classes 6 and 7 are described in a different way than the other classes.  I think the net effect is that the definitions are compatible; however, in reading the document as it stand I wondered if I was missing something different about classes 6 and 7.  E.g., 6/7 do not have an introductory summary sentence, and use symbols <= rather than "upper bound":

   Class 3: Interactive transaction data.  Mean delay upper bound is 400
   ms, delay variation is unspecified, and loss ratio is less than
   10^-3.  Application examples include signaling.

   Class 6: Mean delay <= 100 ms, delay variation <= 50 ms, loss ratio
   <= 10^-5.  Applications that are highly sensitive to loss, such as
   television transport, high-capacity TCP transfers, and TDM circuit
   emulation.

   Class 7: Mean delay <= 400 ms, delay variation <= 50 ms, loss ratio
   <= 10^-5.  Applications that are highly sensitive to loss, such as
   television transport, high-capacity TCP transfers, and TDM circuit
   emulation.

Excerpted from Brian Weis' secdir review:

2. Section 4.4 refers to "the example given in Section 4.4 of [I-
D.ietf-nsis-qspec]". Is that the right section? It discusses 
extensibility of QSPEC, but there's no example.

3. Reference [Y.1221] has "Y.1541" in its title rather than "Y.1221".

4. Reference [Y.2172] has "Y.1540" in its title rather than "Y.2172".
