Nick, your proposed text looks OK if it's clear that "the user's intent" can be determined by out of band means, e.g. by provisioning (e.g. Customer Care request to add a "track me not" feature), or policy (e.g. a corporate proxy which enforces company policy on tracking), or any number of other such means. In essence, the "intent" here can be derived from a larger purpose, e.g. to be safe on the Web or to have a job.

Subject: action-231, issue-153 requirements on other software that sets DNT headers

Hi all,

Dave Singer and I volunteered to draft a very short proposal to capture the idea that if software outside the user agent (like anti-virus software, or a http proxy or what-have-you) sets a DNT value, it should still capture the user's intent.


After this existing sentence in the TPE spec:
> Likewise, a user agent extension or add-on must not alter the tracking preference unless the act of installing and enabling that extension or add-on is an explicit choice by the user for that tracking preference.

> Software outside of the user agent that causes a DNT header to be sent (or modifies existing headers) MUST NOT do so without following the requirements of this section; such software is responsible for assuring the expressed preference reflects the user's intent.

I believe this fulfills a common concept we've heard in the WG. It may also go towards issue-150 (conflicts between user agents), in explaining that any software must follow the same requirements for non-default user choice.

David Wainberg is also working on a proposal around this issue but we haven't had a chance to compare/combine texts yet.
