Manav and co-authors, I just started reading the document, and have a few comments.
First, as we have stated a few times already, TICTOC is looking for a unified solution for carrying timing flows over MPLS, not just 1588. Although this doesn't necessarily mean that a single document explains both, if we have two separate documents, or worse, only a 1588 document, we will not accomplish what we are intending. Second, the following wording is not going to fly in the IETF. This document requires that MLPS nodes (LSRs) SHOULD be able to support TC, ... Such an LSR is referred to as a "1588-aware LSR" in this document. As written this means that if this document becomes a proposed standard RFC, then every LSR manufactured will have to support identification of timing flows (remember SHOULD means MUST unless there is a very good reason no to). This, of course, means that almost every LSR will need to be "1588-aware" and there is no need to define the term. I believe that what you mean to says is something like this. This document defines a "1588-aware LSR" that is able to identify 1588 timing flows carried over MPLS. Third, and more controversially, I believe we should be more modest in our MUSTs here. I would prefer that a "1588-aware" LSR MUST to be able to identify for prioritization, and MAY be able to correct the correction field. I have a few more minor comments (e.g., you speak of correcting FCS for the PW FCS retention mode of Ethernet PWS, but don't discuss correcting the UDP checksum (which in IPv6 is mandatory), but prefer to clear up the major items first.
