I understand Alain's point, the possible confusion about what do in service packs and other types of upgrades, but we went round and round and eventually decided to just leave the text as is. We had a very explicit discussion of this topic during the WG meeting in Minneapolis, and the sense of the room was rather close to Eliot's opinion. In fact, I proposed to change the text to Alain's wording, but Brian Carpenter objected that this would cause more confusion, since we really want to say "MUST not use" to prevent further usage, and "SHOULD" does not achieve that. The sense of the room was clearly with Brian. I guess this is one of the cases where the consensus is a bit rough. -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
