How is this going to be handled? Most testing domains are
using _domainkey or is _dkim targeted for a binary RR?
This is just a typo. A.3 should be _domainkey as well.
I figured as much and this is probably a good idea to clean that up.
Does this related any way to section 22.214.171.124 and a normative reference to a

I could be wrong, but I thought the "plan" was to use _domainkey to offer
some level of backward capability with Yahoo's Domainkey TXT lookup, and
when an official RR type number for DKIM is assigned called DKK and we can
then switch to subdomain _dkim for DKIM binary RR lookups. At which point,
the semantics of section 188.8.131.52 kicks in.
DKK RR Lookup <selector>._dkim.<domain>
TXT RR Lookup <selector>._domainkey.<domain>
I'm fine either way.
