[dane] Reusing TLSA

[Paul Hoffman <[e-mail]>]

I'm starting this as a new thread because Richard conflated two topics *and* missed the fact that there is already a WG document.

The question becomes what the registration of an RRtype "means". If it means the bits on the wire of the *response* and their semantics, then I think the S/MIME document can use the TLSA RRtype. If an RRtype also means the bits on the wire of the request and response, we can't.

Personally, I think that the RRtype is defined just by the bits in the response, so we could reuse, but others might disagree.
