Summary: A clear will written document. Ready for publication.

Major issues: None

Minor issues: Not an issue with the design per se, but there is a school of thought that says do not use all zeros or all ones in a protocol without good reason since these are common uninitialized variable values. If the designers have scope to do so they might consider picking another value.

Nits/editorial comments: 

Slightly strange order of final sections. Most readers will want to look at IANA and Security rather than worrying about the contributors.
