Well, ummm, I think this demonstrates the difference between theory and practice. In theoretical terms -- as far as the global registration scheme goes -- they /do/ have their own name spaces. In practical terms, they adhere to some additional conventions that choose to use the same subordinate one. I suppose some sort of language that notes this possibility -- since it's a popular choice -- is worth adding, to moderate the tone of independence in the current draft. > > - on that note, _sctp and _dccp are missing from the global table. ack. > - the table formatting is pretty poor, do we really need any more > than just "NAME", "RR" and "REFERENCE"?

To the extent possible, I think that it only has to do registration with accountability. There are cases where more stringent requirements make sense, but I don't see this as one of them: there not any danger I can see in a useless registration entry and there's lots of namespace. Thoughts? d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
