Hi Karl,

The points I tried to make here is that
 A) it is testable whether a response header has been sent
 B) it is testable whether this response header contains a field like 'I
promise to implement DNT and I will adhere to the requirement put forward
in the compliance spec'.
C) It is not testable from the outside whether a site in fact adheres to
these promises.

Eg if we were to require 'no recording if IP addresses', compliance is hard
to test from the outside,

huh? :)

A MUST conformance statement has to be testable. If you are saying that an
implementer can NOT test the MUST, then the MUST is meaningless. Or I have
misunderstood what you are trying to explain.
