This is what I have done so far. Here is the RR for a URN authority:

<domain> IN <ttl> URN <produced_on_host> <mbox> (
<preference> ;preference like MX records
<Authority_dname> ;actual host to contact
<port> ;port to contact server on
<Scheme> ;final scheme used to resolve URN
<Signature> ) ;Signature of this record

preference is exaclty like in MX.

port is the port to contact the final resolution authority on.

scheme is the scheme over which you connect.

Signature is the MD5 of the record minus the Signature signed by the
servers private key.

host,port and scheme can all be shoved into a URL if we want to. That part
doesn't matter...
