The draft has been significantly updated to address all the comments received and make the draft more generic.
The authors would appreciate your comments, as well as a quick note to whether the comments posted have been addressed, and if not, what is still missing.

Many thanks!

       This document defines a way for an IS-IS Router to advertise multiple
       types of supported Maximum SID Depths (MSDs) at node and/or link
       granularity.  Such advertisements allow entities (e.g., centralized
       controllers) to determine whether a particular SID stack is
       supportable in a given network.  This document only defines one type
       of MSD (maximum label imposition) - but defines an encoding which can
       support other MSD types.
