COMMENT:
----------------------------------------------------------------------

Thanks for working on this.

I agree generally with the editorial comments others have already made
and I have a few more.

Section 4: 
s/generally RECOMMENDED./RECOMMENDED./
s/a mixture of clients; some supporting/a mixture of clients, some
supporting/

Section 4.2:
I note that this section is silent about the interaction between CT and
the PKIX-TA(0) and PKIX-EE(1) usages. I'm assuming the implication is "go
ahead and use CT if you want to in those cases," but whatever it is,
might it be worth making it explicit here?

Section 10.3:
"A service with DNSSEC-validated TLSA records implicitly promises TLS
   support.  When all the TLSA records for a service are found
   "unusable", due to unsupported parameter combinations or malformed
   associated data, DANE clients cannot authenticate the service
   certificate chain.  When authenticated TLS is mandatory, the client
   SHOULD NOT connect to the associated server."

Seems like that last requirement should be a MUST NOT.

Section 14:
"When TLS is opportunistic, the client MAY proceed to use
   the server with mandatory unauthenticated TLS."

I find the use of the word "mandatory" here confusing -- what is
mandatory in the opportunistic case? Seems like this would make more
sense without the word "mandatory."
