(3) Briefly describe the review of this document that was performed by
the Document Shepherd. If this version of the document is not ready
for publication, please explain why the document is being forwarded to
the IESG.
3 years of review and debate, creation of the NMDA by NETMOD by
I2RS requirements, Review of every comment by shepherd,
Discussion with all parties.
It is validated, debated, check, re-check, and - everyone says ship it.
(4) Does the document Shepherd have any concerns about the depth or
breadth of the reviews that have been performed?
All reviews and reviwers have been have been top quality.

is a need for it. In any event, if the WG has discussed those issues and
has indicated that it still wishes to advance the document, detail those
concerns here.
This document implementations and wide-spread vendor support. It is key for
other topology yang models. NMDA capable model that can be deployed in
configuration datastore or dynamic datastore.
(7) Has each author confirmed that any and all appropriate IPR

represent the strong concurrence of a few individuals, with others
