Reviewer: Henry Thompson Review result: Ready with Nits I'm the designated ArtArt last call reviewer for this draft. This is essentially a _pro forma_ update of the corresponding HTTP/2 document. It's substantially ready to go. Three nits: 1) The readability of the main paragraph of section 2 could, I think, be improved. Instead of "Where [ORIGIN] indicates that the ORIGIN frame should be sent on Stream 0, this should be interpreted to mean the HTTP/3 control stream. The ORIGIN frame is sent from servers to clients on the server's control stream." this should (unless I misunderstand it), be a new paragraph, something a bit more explicit, e.g.: Where [ORIGIN] indicates that the ORIGIN frame should be sent on Stream 0, this should be interpreted to mean the appropriate HTTP/3 control stream: that is, the ORIGIN frame is sent from servers to clients on the server's (unidirectional) control stream. 2) To match the HTTP/2 and IANA registry entries, the table in section 4 should read ORIGIN 0x0c Section 2 3) Again in section 4, it took me rather a long time to chase down the actually relevant bit of the '[IANA] "HTTP/3 Frame Type" registry [HTTP3]', which is not in the referenced document at all. Wouldn't a reference to the think itself, https://www.iana.org/assignments/http2-parameters/http2-parameters.xhtml#frame-type, be better here? ht -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
