Section 1:

Current issues #1 says "use TXT or new RR?  (ATB: new RR, but TXT for now)"

Is there a single person here who believes this? Once implemented as
TXT, I give the odds of seeing a specific type record being implemented
as less than zero. Pick one, don't tease.

Section 2:

I am vehemently against adding yet another large TXT record at the apex
of zones. Everybody and their brother wants to jam something there. We
are polluting the apex to such a point that it will no longer be
possible to answer TXT queries via UDP even with EDNS. If you MUST use
TXT, please prefix the name with an application-specific value.

We're aware this subject has been covered a few times previously, especially in the DBOUND drafts, but we're hopeful that a more simple approach might be more acceptable.   The secondary domain will create a DNS record that shows a link to a primary domain, and the text should be able to be validated using the public key in a DNS record the primary domain shares.  This is something akin to DKIM, a mechanism that the email world uses to ensure the contents of a message have not been tampered with.
