Thank you for making progress on this draft. 

One question I had related to the text that says 

“Registrations MUST reference a freely available, stable specification.”

In other documents, people have argued for that but that means that 3GPP (and others) would not be able to use the mechanism which seems bad. 

In the name of broad use and getting done, I would prefer to just use "Specification Required" from RFC 5226. 

But if we don’t do that, we better specify what we mean by “free” in this context.
