That would be fine except that the Port and Service registry has thousands of 
entries, and the named ones (nearly all of them) are valid SRV names. Importing 
a handful of names that we guess are commonly used with SRV is the worst of 
both worlds.

Either point at the real registry for SRV, or say that this explicitly 
redefines the namespace for SRV and see if dnsop will go for that.  I don't see 
any way you can just ignore RFC 6335 and its predecessors.

I belive that's correct, but again, either we deprecate URI or we deal with its 
naming rules.

To get rid of special, add another column to the first table which identifies 
the second level namespace.  In some cases it's empty, in some cases it's Ports 
and Services, in a few it's Enumservice, and in the rest it's the second table.
