Hi again,

Sorry one more thing on references: There are two normative reference to obsoleted RFC (RFC2141 and RFC4148). I think it would be more appropriate to make these references informational instead. Also there is a new Downref to RFC6248, however, I think that could also be an informational reference instead.

@Bill: as the document shepherd it would be could to point out these things in the shepherd write-up. If the authors/group decides to move these references to informational, there is no additional action require from you. However, if not, the write-up should be updated accordingly.

I believe what we usually do is to request the new entry before IESG evaluation and simply document in the RFC that an registration was performed, or in case of e.g. the port registry (where however the policy is IETF Review for system ports) we ask the experts for review during the IESG evaluation process and take this as input for the IESG to make a decision on approval (rather than as input for IANA). I’m cc’ing Michelle, as I understood that she was already involved in reviewing this document, and she might have further insights/considerations.
