Re: ACTION-390: alternative UA affordances for DNT choice

So it sounds like we're in agreement re: concept, but might be in
disagreement re: the language. I've modified some of the language suggested
by Adrian. Does this address your concern? IMHO, "The User Agent MUST
ensureŠ" seems pretty clear and covers your music service scenario.

If not, what do you think needs to change?


1.    User agents are responsible for determining the user experience by
which a tracking preference is controlled;
2.     User agents MUST ensure that tracking preference choices are
communicated to users clearly and accurately and shown at the time and place
the tracking preference choice is made available to a user;
3.     User agents MUST ensure that the tracking preference choices
accurately describe the parties to whom DNT applies and MUST make available
explanatory text to provide more detailed information about DNT
functionality.
