dkim-base: _domainkey vs _dkim

The document refers to both _domainkey vs. _dkim subdomains to DNS DKIM
records:

| 3.6.2.1  Name Space
|
|    All DKIM keys are stored in a subdomain named ""_domainkey"".  Given
|    a DKIM-Signature field with a "d=" tag of ""example.com"" and an "s="
|    tag of ""sample"", the DNS query will be for
|    ""sample._domainkey.example.com"".

and

| A.3  The email signature is verified
|
|    The signature is normally verified by an inbound SMTP server or
|    possibly the final delivery agent.  However, intervening MTAs can
|    also perform this verification if they choose to do so.  The
|    verification process uses the domain "example.com" extracted from the
|    "d=" tag and the selector "brisbane" from the "s=" tag in the "DKIM-
|    Signature" header field to form the DNS DKIM query for:
|
|    brisbane._dkim.example.com

How is this going to be handled?  Most testing domains are using _domainkey
or is _dkim targeted for a binary RR?
