Reviewer: James Gruessing Review result: Ready This is my review of draft-ietf-httpbis-binary-message-04 as part of ART Last Call review. Overall this is a concisely written document, and although the specification makes it clear that its format is distinct from existing framing defined within HTTP/2 and HTTP/3 (in addition to borrowing elements from QUIC) readers who are not already familiar with these may be at a considerable disadvantage trying to understand this document. Editorial Comments: Section 3 is quite difficult to grok, and I agree with the suggestions made by David Schinazi in his Gen-ART review. However as one additional minor suggestion is that references to section 4 within section 3 appear repetitiously, and as section 4 doesn't provide specific guidance for each of the invalid message scenarios but generic text I'd suggest you include "invalid message" as a definition in section 2 that states all usage of the word is applicable to section 4. Section 6 - As a suggestion I would propose the normative text around pseudo-fields instead be placed within appropriate sub-sections of section 3, keeping section 6 exclusively informative. Asides from this there are no further nits or major issues to mention. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
