I have been looking for the IANA registry in which the IDNA prefix xn-- is
allocated and have not been able to find it. I can see the following
possibilities

1) There isn't such a registry. The allocation is purely ad hoc

2) There is a registry but none of the IDNA RFCs bother to list it as a
normative reference.

Either one would be bad. The existence or non existence of a registry, the
allocation or non allocation of a code point is not going to cause me to
decide whether or not to use functionality. All that the registry achieves
is to avoid collisions.
