s/Its/It was/ That is, -05 is the result of going through those issues.

> The most interesting thing to note about it is the configuration primitive has changed slightly from a URI with a particular set of query parameters to a URI Template. The example should illustrate how these things are broadly similar but allow a degree of flexibility for future media formats fitting into DoH. This flexibility came up in London, and in the github discussion both before and after we met so we tried to find the right balance between flexibility and complexity. I think what is in -05 balances those needs while leaning towards simplicity.

The fact we were making a (small) breaking change to the wire format for queries might raise objections, but given that the document still isn't in WG Last Call, much less IETF Last Call and IESG review, should cause developers to keep a bit nimble.

Hopefully the examples are still clear. Do note the differences in the diff at <https://tools.ietf.org/rfcdiff?url2=draft-ietf-doh-dns-over-https-05.txt>.
