Document: draft-ietf-lamps-cms-mix-with-psk-05 Reviewer: Robert Sparks Review Date: 2019-07-30 IETF LC End Date: 2019-08-06 IESG Telechat date: Not scheduled for a telechat Summary: Essentially ready for publication as a Proposed Standard, but with an issue to address before publication. Issue: The instructions for IANA are unclear. IANA has to infer what to add to the registries. I think they _can_ infer what to do for the IANA-MOD registry. It's harder (though still possible) to guess what to do for IANA-SMIME. They also have to infer the structure of the new registry this document intends to create. Explicit would be better. Also, the document anticipates the currently non-existing anchor to the new registry in the references (security-smime-13). That generally should also be a tbd to be filled by IANA when the anchor is actually created. Nits/editorial comments: Section 5, 1st paragraph, last sentence: "make use fo" should be "makes use of" Section 9, 1st sentence : "in the Section 5" should be "in Section 6". (That's two changes - the removal of a word, and a correction to the section number). Micronit: In the introduction, you say "can be invulnerable to an attacker". "invulnerable" is maybe stronger than you mean?
