Re: [ietf-dkim] (registered) domain name (Re: errata revision: opaque)

well, now I'm completely confused.  to my eyes, your example fits exactly what 
'registered' and 'resolvable' mean, but I guess you have something else in mind.

RFC 1034 and RFC 1035 make many references to resolvers.

We could, but it's not actually a requirement that the SDID resolve  
in  the DNS (and in many cases it won't).

Really?

Then how does the receiver obtain the public key for performing  
verification?

key retrieval is defined as using d=.

If you receive an email with a selector of banjo.aardvark and an SDID  
of hatstand.beartrap.blighty.com then you'll hopefully be able to  
resolve banjo.aardvark._domainkey.hatstand.beartrap.blighty.com, but  
that's all you can say about ability to resolve any query in the  
domain tree under the SDID, including the SDID itself.

At least, that's how I understand it.

Cheers,
   Steve
