A third-party tracker might use a machine-readable policy (for example, P3P) or some indication of compliance with a self-regulatory program or auditing practice . Users that care to might configure their user agents to grant exceptions (and thus send DNT:0 signals) to trackers with such practices.

I was trying to get at the more general point that a user might configure their browser to send DNT:0 to a set of domains or resources based on some other signal besides a JavaScript-initiated exception request. This text isn't meant to recommend any particular UA implementation (this is non-normative text), but to note the possibility of UAs that granted exceptions based on the presence of a particular P3P policy, an indication of participation in an industry self-regulatory program, or some other insight into the relevant data handling practices.
Happy to accept a suggestion of clearer text on this point, or to explain further.
Thanks,
Nick
