> Excuse me, but I really cannot fathom why we are saying that this draft defines a new protocol when it is an explicit goal for all existing implementations to continue to work. How can this be a new protocol when all implementations implement this already?

All host implementations have to work.   In order for them to work, new router behavior has to be specified.   That sounds like a protocol spec to me.  My question would be, why is this a problem?   I think that the document could be clearer about required behavior, but it already basically says what needs to happen.   Discussing this with Suresh on Saturday morning convinced me that more clarity would be useful, but that seems like a pretty easy problem to solve.
