RE: Issue-207

Only offering a list of reasons why the signal "might" be disregarded does not improve transparency and encourages arbitrarily ignoring of DNT. As there is no way to add qualifiers to the TSV we either have to 1) come up with a mechanism in the TPE to report qualifiers, or 2) add a further set of single character values to signal different disregard reasons, or 3) abolish the "D" signal or 4) reiterate the note in the TCS that a disregard response is assumed to be an exceptional event.

My vote would be for 3, i.e. Jonathan's point but if that is too radical we should at least do 4.

So:

A third party to a given user action that disregards a DNT signal MUST indicate so to the user agent, using the response mechanism defined in the [TRACKING-DNT] recommendation. (5.0 4th para)

Becomes:
A third party to a given user action that disregards a DNT signal MUST [indicate its reason for doing] so to the user agent, using the response mechanism defined in the [TRACKING-DNT] recommendation. This specification is written with an assumption that disregarding DNT would only be used in situations that can be adequately described to users as an exception to normal behavior. If this turns out not to be the case, either the server's decision to disregard the signal needs re-examination, or this specification, or both.
