Please wait for direction from your document shepherd or AD before posting a new version of the draft. Document: draft-ietf-xrblock-rtcp-xr-pdv-03.txt Reviewer: Alexey Melnikov Review Date: 23 July 2012 IETF LC End Date: 23 July 2012 IESG Telechat date: N/A Summary: Almost Ready Major issues: None Minor issues: In Section 4: pdvtype = "pdv=" 0 ; MAPDV2 ITU-T G.1020 / 1 ; 2-point PDV ITU-T Y.1540 Firstly, I think you meant "0" and "1" above (you are missing quotes). Secondly, this doesn't allow for future pdvtype registrations, so you should be using something like 1*2DIGIT here (with a comment that value 0-15 are valid), or something more specific. The document creates a new registry with "Specification Required", yet the shepherding write-up says that the document doesn't create any registry with Expert Review (question 18). So one of the two is incorrect, I don't know which one. Nits/editorial comments: None
