To my knowledge, there has never been a requirement to document all copyright holders of material in documents approved under RFC 2026 or RFC 3978. There is wording that require "all major contributors" to be mentioned, but it seems possible that some part of a document is copyrightable but not be a major contribution. So, how would you actually know which old contributors to contact? Any what if the contributor is deceased? It would be very useful if the IAOC/Trust develop, together with legal aid, guiding instructions for this situation. It would answer the common questions. It seems applicable to a lot of work that will happen in the next 5 years: updating any RFC issues prior to RFC 5378. /Simon _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
