Re: [mpls] Working Group Last Call on draft-ietf-mpls-msd-yang

Thanks for confirming Ketan.

Tarek - I think we can finally request publication of this draft. 

Thanks,
Acee

The draft only included MPLS MSD at the beginning, then Ketan suggested we follow the IANA MSD types registry, so we added the iana-msd-types.yang module, which also includes SRv6 MSD types. The ietf-mpls-msd.yang augments the base MPLS model defined in RFC 8960, and it can only query MPLS MSD types. Note: there are msd-base-mpls and mpls-base-srh defined in the iana module to separate MPLS and SRv6 MSD types.

But the title and abstract of the draft claims that the YANG module is defined for MPLS MSDs, without mentioning SRv6. It confused me a little bit.
