Reviewer: Linda Dunbar Review result: Ready with Nits I have reviewed this document as part of the Ops area directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the Ops area directors. Document editors and WG chairs should treat these comments just like any other last call comments. The document describes using SCHC Header compression mechanism to compress CoAP headers. The mechanism is clear. Some Nits: - using many acronyms without explaining them, such as MSB, TV used in several places. It would be nicer to expand the acronyms when first use them. - Page 4: "... a request may contain an Accept option and the response a Content option". Should you add a "... the response contain a Content option"? Linda Dunbar
