An additional (and separate) comment on the DNS discovery draft.

Temporarily suspending my disbelief in the mechanism described in this
document for purposes of discussion, there's a terminology problem:
the draft talks about finding DNS resolvers, which is not really right
and which some readers have told me they find confusing.

To be clear: this issue is not the fault of the document authors, the
underlying DNS terminology is somewhat confusing and frequently
misused.  It turns out that there is no good short name for the entity
that this mechanism is trying to locate, because the DNS terms "name
server" and "resolver" really refer to protocol roles rather than to a
particular kind of server.  This draft is talking about finding an
entity that implements both name server and resolver roles, with the
name server role acting as a front end for the resolver role under the
rules described in the protocol spec for queries with the "recursion
desired" bit turned on.

The usual way of referring to this kind of entity is as "a name server
that offers recursive service", often abbreviated as "a recursive name
server" or just "a recursive server".  Some implementations have their
own terminology for the various possible combinations of the name
server and resolver roles, but the terms I'm using here are based on
the protocol specification rather than any particular implementation.

Thus assuming that the WG decides to go forward with this draft in
spite of my objections, for clarity I would recommend that the draft
be changed to use the above terminology (use the full phrase the in
the introduction to define one of the abbreviated terms, then use the
abbreviated term throughout the rest of the document).
