[DNSOP] Registry of non-service _prefix names?

["John Levine" <[e-mail]>]

Over in the dbound working group we have some proposals that would use yet another
underscore prefixed name to avoid name collisions.  (It's not a substitute for a
new RRTYPE; they need the prefix whether the data is TXT or a new type.)  In
the mail world we have _domainkey and _dmarc and likely others.  DANE is
proposing prefixes for publishing PGP and S/MIME keys.

The services registry from RFC 6335 includes all the names for services, but
not the prefixes for things that aren't services.  How hard would it be either
to update 6335 to provide for non-service names, or a new non-service registry
with the understanding that it shares the 6335 FCFS namespace?

R's,
John
