I note that you have the same spelling mistakes as draft-qu-mpls-mpls-msd-yang which usually indicates plagiarism, not that there is anything wrong with that in the IETF! I note that while the two I-D have the same name listed, the e-mail addresses are slightly different.  I have included one of those as cc:.

I say this because both I-D puzzle me in the same way.  What is node-msd that it is a list keyed on msd-type?  And what is msd-type for that matter, same in both I-D?

I understand a node having an MSD, the lowest of those on a link but how can that be a list and why key it on msd-type which appears to be the signalling protocol in use?  I do not understand.

I note that in -08 node-msd was not a list and that f made more sense to me.

If a list is needed, then I think that you need to say why, how it is used - or reference another SR I-D/RFC where it is explained - and why it is keyed on what it is keyed on.

Equally fundamentally, what has node-msd got to do with te or topo or MPLS or ...  I see it as a property of a node which would ideally be part of a base definition of a node even if SR was not in use or part of a base SR augmentation as opposed to what we seem to be getting of  multiple I-D creating their own definitions.

I will post some editorial comments separately.
