Reviewer: Jouni Korhonen Review result: Has Nits Summary: Ready with editorial nits. Major issues: none Minor Issues: Editorials o The document does not pass IDnits. ** Downref: Normative reference to an Informational RFC: RFC 2818 This is obviously intentional but I did not see any mention of this e.g., in the proto write-up. -- Obsolete informational reference (is this intentional?): RFC 5988 This should obviously be 8288 as it obsoletes 5988. o line 256 s/clients SHOULD not/clients SHOULD NOT o line 146 s/The origin frame/The ORIGIN frame o line 429 What does "case-normalization" mean? I could not immediately find that expression, at least not in the referenced RFC6454. If it means making the ORIGIN header values lower case, just state that.
