I don't think that's true. We're talking about a registry established by RFC 3969, which says: "SIP and SIPS URI parameters and values for these parameters MUST be documented in a standards-track RFC in order to be registered by IANA." ...and... "For the purposes of this registry, the parameter for which IANA registration is requested MUST be defined by a standards-track RFC." These are not ambiguous statements. We just botched our communication with IANA. But I think we can do the right thing here without going back and fixing all of the issues with our ancestral documents. I mean, sure, maybe we should clean that up too, but I don't see the value in blocking new work on doing so. In terms of publishing draft-mohali-dispatch-cause-for-service-number, I think there are two reasonable paths forward: The first would be forming consensus that the two statements I quote from 3969 above -- and the reinforcing statement in 5727 -- were all incorrect, and that we want to explicitly (i.e., in a new document) reverse those statements and update the corresponding registration policy. Then, we publish -mohali- as informational.[1] The second would be implicitly accepting established consensus around this registry, and consequently changing -mohali- to PS. Rather than figuring out which of these is easier (clearly, the second is less work), I think the real question here is: do we think we got the registration policy for SIP URI parameters wrong? /a ____ [1] We *might* or might *not* also decide to then do something about RFC 4458 in this case, but that's a completely separate decision.
