Document: draft-ietf-kitten-pkinit-alg-agility-05 Reviewer: Christer Holmberg Review Date: 2019-03-01 IETF LC End Date: 2019-02-17 IESG Telechat date: 2019-03-07 Summary: The draft needs to be more clear on how RFC 4556 is updated. Major issues: None Minor issues: Q1: For the unfamiliar reader, it is unclear exactly how RFC 4556 is updated. There is e.g., no text indicating what sections of 4556 are updated, and there is no "Updates to RFC 4556" section. I assume the remainder of the draft then updates RFC 4556, but I think it needs to be more clear for the unfamiliar reader. Even if a "Updates to RFC 4556" section would not be feasible, the document should indicate what parts/sections of 4556 are updated, and what sections in the draft defines those updates. Nits/editorial comments: Q2: Both the Abstract and the Introduction start with "This document updates PKINIT,..." I think it would be good to first give some background information on the issue(s), and then state that the document fixes those issues by updating RFC 4556.
