We say DNT should represent an expression of the user's preference. 

DNT:1 means "please respect the compliance document and tell me
DNT:unset means "I have no clue or I do not care or I'm not 
configured yet"
DNT:0 means "I see you want to track me and that is ok" (within the 
boundaries of my local law". 

In the absence of all local data protection/privacy law, unset and 
DNT:0 are equivalent. But if you hit a sectorial privacy law in the 
US or if you want to track in the EU (above the Radar), then you 
need an affirmative user expression that you can record. Whether the 
TPE or the Compliance Spec will be sufficient for EU law is a thing 
I had the assumption, we are working on. And as I understood Rob, we 
may issue a Working Group Note that explains what we believe must be 
done in addition to DNT implementation to express consent. I think 
it would be good to have that in a separate document. But on the 
other hand, if we tear down the foundation of the expression and 
communication of consent by removing DNT:0 we can just forget about 
all this and tell the EU folks to move on and forget about DNT. The 
banners about cookies on UK sites are nice, aren't they? This is 
what you get if DNT:0 fails. 

Best, 

Rigo
