uh huh; some stray thoughts on this I-D

s.9
   MITRE has approved this document for Public Release, Distribution
   Unlimited, with Public Release Case Number 19-3027.

Is this the beginnings of an IPR issue to be resolved? I don't know.


YANG Model for QoS

QoS is a very general concept for me, seeeing it more in the context of
system and application performance rather than just network so I would
like something in the title to make it clear that this is 'only'
routing;  ditto - especially - the Abstract.  Current RFC have something
in the title that makes this clear.

s.1
(NMDA) [RFC8342 [RFC8342]].
looks odd with [[ ]]

YANG has conditionals which many modellers overuse (IMHO:-)
Here I would like more.  You twice have min and max and so could require
that max> or >=  min.  Is it valid to have the one value, ie min = max,
or just a min?

should not have the WG chair therein- they are too ephemeral ! - just
web, list, editors

There is a mismatch between the editors of the I-D and those of the YANG
modules; is this intended?

References in the YANG module - I would like more! e.g.
  identity one-rate-two-color-meter-type {
       base meter-type;
       description
         "one rate two color meter type";
     }
     identity one-rate-tri-color-meter-type { ...
        reference  "RFC2697: A Single Rate Three Color Marker";
     identity two-rate-tri-color-meter-type { ...
       reference    "RFC2698: A Two Rate Three Color Marker";

while some modules lack any such references for the identity; needs to
be consistent

or, still on Reference,

     grouping protocol-cfg {
       list protocol-cfg { key "protocol-min protocol-max";
         description  "list of ranges of protocol values";

which I read as being IPv4 only - IPv6 does not have protocol!  Perhaps
a name change or explanatory note plus a reference to the IANA website.


           choice drop-algorithm {
has only one case; if intended, an explanatory note would be useful


     augment "/if:interfaces/if:interface" {
is unqualified so this will be added to all interfaces in the box; I am
unclear if this is a good idea.


IANA !

Security !
