I don't like it but it seems we should have one.

So I'm in favor of adopting this document.

Some comments so far:

Normally we try to leave "private use" ranges in registries for people
to experiment on. It would be good to have that here as well, or else we
won't be able to differentiate experimentation from standarization. I
suggest reserving the double underscore space (__*) for private use
(provided this isn't already in wide use)

The document should probably explain the RRtype listed in the registry
and interaction/allowance with CNAME/DNAME.

Are there any known already existing conflicts where two protocols use
the same underscore entry. If so, how do we resolve that issue?

What are the requirements for entry into this registry. I would not want
to see a rush of people registering vanity names for pet projects,
taking away all the sensible one word entries. I see _mail is available :)
