Hi Tom,

Thank you for your comments.

Regarding s.9, in the case of this draft, it is not the beginning of IPR issues
to be resolved.  MITRE has no IPRs to disclose related to this draft.

Regarding the rest of your feedback, my co-authors and I will review and
make the necessary changes in the next revision.  We can revisit each
comment when we publish the next revision.

Thanks,
Helen

        uh huh; some stray thoughts on this I-D

           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 !
