Re: tracking-ISSUE-150: DNT conflicts from multiple user agents [Tracking Definitions and Compliance]

Rigo -- designing the spec in a manner that lets servers expressly 
invalidate a DNT-1 within the context of the spec seems a bad idea. I'd 
actually prefer to leave it as is (not necessarily in a fog, but leave 
it to the server's discretion whether they think they can ignore a 
valid-seeming signal or not instead of giving them the right to capacity 
to invalidate a signal).

Unless you want to take the further (and highly complicated) step of 
providing a mechanism for UAs to confirm 'non-compliant' DNT signals 
with the user and respond with a re-affirmation....
