My first thought was that IANA registries are hard to reference, and you get
this, and suggest XPath.

How to reference things which are not yet created... I actually think that
maybe we need .iana-future, which gets changed at or before AUTH48 to ".iana"

Agreed.
I also think we need some interoperation with YANG, and I think that YANG
also needs ".iana"
