Re: Tracking Protection Working Group draft charter

Hi Nick,

I took a look at this and I have a few comments/questions.

Section 1:

"The Working Group will produce Recommendation-track specifications for a simple machine-readable preference expression mechanism ("Do Not Track") and technologies for selectively allowing or blocking tracking elements.

Proposed candidate technologies for this preference that the Working Group will consider include, but are not limited to, the use of an HTTP header to signal the preference and a site's response, and the use of a ECMAScript API or DOM property for the same purpose."

Are there no proposed candidate technologies for "selectively allowing or blocking tracking elements"? I find the transition from the first paragraph to the second a bit confusing; the first paragraph seems to talk about two specs (preference mechanisms and selecting blocking mechanism), but the second paragraph only addresses one of those.

Section 1.2:

Might be good to explain the relationship between the output of this group and the P3P specs.

Section 2:

"Tracking Preference Expression Definitions and Compliance, Recommendation.
This specification defines the meaning of a Do Not Track preference and sets out practices for Web sites to comply with this preference."

Will the definitions/compliance item be normative? That is, will the practices it "sets out" be mandatory to implement (for some population of web endpoints)?
