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   http://wiki.tools.ietf.org/area/gen/trac/wiki/GenArtfaq   Document: draft-ietf-appsawg-http-problem-01 Reviewer:  Dan Romascanu Review Date: 11/30/15 IETF LC End Date: 12/4/15 IESG Telechat date:   Summary: Ready (with one clarification question).   A very useful, clear and well written document.   Major issues:   Minor issues:   One question which may be a matter of clarification rather than an issue:   In Section 3:   Ø   If such additional members are defined, their names SHOULD start with a letter (ALPHA, as per [RFC5234]) and SHOULD consist of characters from ALPHA, DIGIT, and "_" (so that it can be serialized in formats other than JSON), and SHOULD be three characters or longer.   What is the rationale here for the SHOULDs? What are the exception cases that require using SHOULD rather than MUST in this paragraph?   Nits/editorial comments:
