Dear Stewart, Dear Sasha, I think there are already enough contributions in that direction I (with many other experts) contributed to in the form of IETF mailing list discussion and ITU-T liaisons. Unfortunately I regret to say that some questions for clarification and concerns risen in those emails (for sure some of mine) still remain without an answer. At the same time, some comments provided by ITU-T liaisons still remain unresolved.

Such a draft needs to be technical, and describe the actions that the network operator is unable to perform, or the fault cases that they are unable to diagnose using the OAM defined in the IETF RFCs, or late stage WG drafts. Alternatively if you are referring to a bug in the MPLS-TP OAM protocols, you need to tell the community what it is. I believe that this request has been made a number of times, in various forums, and, as far as I know, no document has yet been produced. An argument of the form "you must standardize what I want" will not fly. What is needed is a very clear technical definition of the issue(s). When we have the "major unresolved technical concerns" on the table, we will be in a position to determine the best disposition of those issues.
