The one comment we wanted to have a bit more discussion before
deciding how to proceed is this:

[Section 7.4]

* I think that another requirement should be that the initiator MUST NOT act on 
more than one valid path_response or path_drop message for each path_challenge 
message that it has sent.
ยง7.4 currently says:  "The responder MUST send exactly one
path_response or path_drop message for each received path_challenge."

So it's not clear how a situation with multiple occurrences of
path_drop/path_challenge could come off, if the responder obeys the
specified MUST?

Could you clarify your concern a bit more?
==>MT
Right, I was thinking of spelling out how the initiator should behave if the responder does not comply with the specification.
If that can be excluded altogether or a safe behavior at the responder 
is obvious/implied, then the current text is just fine.

[Section 10]

* You will need to add a new subsection that provides expert review 
instructions, for the Designated Experts assigned to the new subregistry 
defined in Section 10.3.
Thanks: this made us realise that expert review was a bit too
lightweight, therefore we moved to STD required.
==>MT
That makes sense.

Best,

cheers, thanks!
