I think having one policy listed in IANA and another in the RFC counts. I offer as evidence of said lack of clarity the fact that RAI got things wrong with 4458 (My typo of it as 4588 above upthread couldn't help, either) :-) > > But I think we can do the right thing here without going back and > fixing all of the issues with our ancestral documents.

I think a potential third option is to consider whether -mohali- really needs to modify the registry.

Both 4458 and -mohali- define protocol. Reviewers have objected to that as well.
