Tom,

Much as I appreciate your comments, and I agree with the technical
aspects of them. The references and the inconsistencies should be
fixed. However, I have a little bit different view of what should
be done.

It is clear that we need a YANG module for LSP Ping.

It is unlikely that there will be another document.

This document has been very slow developing, the first version is
from 2015.

I think that we should say that this is "a good enough starting
point", and that there are thing that need to be fixed before
publication, e.g the RPCs mentioned by Acee, and the lack of references
and the potential inconsistencies pointed out by you.

To put the working group in control of the draft and make sure that it
progress well I want to adaopt it as a working group document. The
only thing I believe is necessary is that the authors acknowledge that
the issues pointed out needs to be addressed.

/Loa
