Hello Lotte and all, I've put a new intermediate revision on Github. I'd like to publish it to the IETF directories with your approval. It includes extensive changes from "node" terminology to "address" terminology wherever appropriate, and gets rid of the "Ndx" terminology in favor of the lists that include null elements. Lotte, if you have text for the purpose of improving the description for supplying protocol elements to RFC 5444 (e.g., OrigAddr with OrigSeqnum, etc.) please let me know. I am willing to help finish it once I get the basic idea of what you want to do. It would be nice to put this into the above-mentioned revision. It would be nice to do this as a Christmas present to [manet]. Regards, Charlie P.
