I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the IETF Chair. Please treat these comments just like any other last call comments. For more information, please see the FAQ at . Document: draft-ietf-ippm-twamp-time-format-?? Reviewer: Joel Halpern Review Date: 2017-03-02 IETF LC End Date: 2017-03-15 IESG Telechat date: Not scheduled for a telechat Summary: Major issues: Minor issues: The wording of the behavioral requirements for signaling in section 2.1 is atypical for IETF documents (and in my view makes it harder for the reader to follow.) The rules are listed as separate rules, but they are actually sequential steps that must be test in order, exiting the process if the condition for each step is met. But it does not actually say that. Nits/editorial comments: Section 2.3 refers to this as a proposal. It is a specification, not a proposal. Please reword.
