And defining the YANG models for MPLS MSD and SRv6 MSD in separate documents seems a little bit unnecessary.

While the SRv6 augmentations (including those for MSD) will be in a separate document with the rest of the SRv6 stuff. Best to keep them together and not hold of MPLS. The question is whether or not we need to remove the SRv6 identities from inna-msg.yang and add them back as augmentations in the SRv6 document. 

Thanks,
Acee

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.
