I have reviewed the document and it is in good shape. The document has a few nits found by the idnits tool. The string "RFC" should not be included when specifing "obsoletes:" or "updates:". Also the abstract mentions that the documents obsoletes or updates documents that are not listed by the obsoletes/updates headers. In 3.1.1.4. paragraph 4: "participation for those unable to to attend in person." Double "to". I'm wondering whether any of the references should be normative, but it may not make sense for this document.
