For usage 2, Yes. That's probably why Viktor and Wes wrote in section 3.9.2 of their BCP document that TLSA RR 2 publishers must ensure their servers are configured to serve the trust anchor cert as part of a full cert chain, when TLS handshaking. I'm thinking to add annotations to that effect in the test site.

Usage 3 specifically does not require PKIX validation, so the root cert non-availability is moot. If DANE comes to be widely deployed and trusted, backed by effective DNSSEC, then it seems likely that Usage 3 will come to be the default mode of operation, as either 301 or 302, for brevity.

Perhaps I should repeat parts of the BCP in the respective test cases.

Stephen.
