Re: [TICTOC] draft-ietf-tictoc-1588overmpls-06 comments

Hi Peter,

This wasnt intentional. Let me take a look at why certain sections got
removed -- i think its an editorial issue.

Moving from draft-04 to draft-05 there was a significant effort to understand how TC (both P2P and E2E) and BC work with LER and LSR and there seemed to be agreement on the draft-05 text on that topic (I worked a good deal with Shahram on the text).
