I share Joel's concern - it does seem premature with the undecided or unresolved issues relating to NRP (or whatever name emerges)

Meanwhile, I looked at the YANG

Normative references are required for

6991 -
8294 -
8519 -
8776 -
draft-bestbar-teas-yang-topology-filter

and for whatever contains srv6-types which is not a module I can find in IANA

'This draft defines ...'
perhaps 'document'

The document title is sometimes spelt as a plural but more often in the singular

NRP would benefit from a reference where it first appears.

SLO SLE need expanding on first use

        WG Web: <http://tools.ietf.org/wg/teas/>
is out of date twice

         "RFC XXX: A YANG Data Model for Network Resource Partition";
perhaps
         "RFC XXXX: A YANG Data Model for Network Resource Partitions";

             leaf maximum-bandwidth {
what are the units?

         presence "indicates NRP IGP congruent";
I think that congruence needs defining.  If two triangles are congruent, then I know what must be the same, what must be different.  I do not have that understanding for network topology

         units "bps";
bits or bytes?

         "Introduces new network type for NRP topology";
reminds me of a decrepit and rusty sign  on the road near me that announces a new road layout, dating from over a decade ago.

   The following individuals, authors of
   [I-D.bestbar-teas-yang-nrp-policy] and [I-D.wd-teas-nrp-yang],
   contributed to this consolidated document:

Should that also include
draft-wd-teas-vtn-network-yang-00.txt 6jun21 22pp
If only to point out another name change in the predecessors?
