Further thoughts on -16 (as my previous comments included below are).

What is the status of Appendix B?  I find this a thorny question.
Appendices are usually regarded as not Normative, with a statement
called for when it is otherwise.  This is a YANG module which non-NMDA
servers will implement so that says it is Normative, to me.  On the
other hand, the world is going NMDA - I do not know how fast - so this
is more like Historic; or non-Normative?

I do not know the answer but do know we can expect to see this several
times, so I am thinking that some thought and guidance from an Ops AD
would be valuable.

IANA Considerations should have a
      reference:    RFC XXXX
for each module registered

Additionally, my comments about the YANG module in the body of the
document apply to Appendix B and C namely
- [RFC ... looks wrong in a YANG module
- import without reference

Does the YANG module in Appendix C need a Copyright statement?

Should the YANG module in Appendix C be registered?  It took a while for
the IETF to see the need to define formally such things as
example.com
so I am thinking it probably should be lest we get many different
varieties in the wild.

And I would like a Note to the RFC Editor asking them to update the
dates with the date of publication especially since there are five such
dates rather than the usual two.
