Greetings again. As you can see, Patrick and I just published -11 to match the recent WG discussion.

The diff is long because we changed "DNS API" to "DoH" (and "DOH" to "DoH"); we actually looked at each instance to make sure it made sense, but if you find any place where it is now not clear, by all means let us know.

It felt like most people agreed with having the 64K limit in the media type being defined here as long as other media types can be defined in the future, which of course they can be. 

The recent AXFR discussion caused us to re-look at the discussion of HTTP and DNS error handling, and we realized that it was spread over a few different places. We combined it into one so that HTTP folks can understand more about DNS error codes, and DNS folks can understand more about HTTP error codes.

We think -11 is ready for the WG chairs to pass on to AD for IETF Last Call. The architecture discussion is important, and will probably continue in IETF Last Call, but shouldn't hold up the protocol document.
