Hi Tarek,
thank you for your thoughtful consideration of my comments. I've reviewed
the diff and got several follow-up notes:

   - the new text in the Introduction section explains the ISD as being
   encoded as labels:

within the label stack, e.g., encoded as labels, referred to as In

     Stack Data (ISD), and

I think s/as labels/into label stack elements/ makes the text a bit more
accurate. What do you think?


   - in my earlier comments, I've noted that the informational RFC 8596
   appears not posing any requirements for enhancements in the MPLS data
   plane. If I am missing something, please let me know.
   - I might have missed it earlier. The TSN is the term used for a very
   specific technology developed at IEEE to support, for example, URLLC
   services. The DetNet WG defines the methodology in support of these
   services using IETF technologies - MPLS and IP. I think it would be
   appropriate if an IETF document refers to Deterministic Networking, not
   TSN. What is your opinion?

Regards,
Greg
