I stumbled across this while reading the TPE diff on last week's call. http://www.w3.org/2011/tracking-protection/drafts/tracking-dnt.html#transitive-exceptions Section 7.6 contains a rather complicated description of what a second third party must do when it receives DNT:0 data received from a first third party because the first third party has been granted a site-specific UGE via some site's first party, wherein the second third party is required somehow to use a TSV of "C" (even though that is quite impossible unless the user agent is making a request directly to that other third party, which would make them a first third party) and also a qualifier of "t". This has so many problems that I have difficulty even stating them. 1) the UA sent DNT:0, so we have no further requirements ... there is no option in DNT for a user agent to tell a third party that "you can track me but don't share any of that tracking stuff with some other third party". 2) there is no request to the second third party, so they cannot respond with "C" even if they could distinguish this new meaning for DNT:0 3) there is no "t" qualifier defined by TCS. 4) this section is all about Compliance, so doesn't belong in TPE. I would like to delete 7.6. Please. If not, we should at least delete its last three paragraphs. If deleted, remnants of 7.6 could be moved to TCS, though I personally believe that none of it would work. My guess is that the "G" response is a better way to address these issues, in general. ....Roy
