Alternative Text for DNT: 0 (ACTION-209, ISSUE-148)

Normative:

i. In General

A DNT: 0 exception allows a website to conduct specific practices that are otherwise prohibited by this specification.

ii. Explanation Requirement

When a website requests a DNT: 0 exception, it MUST clearly explain those practices to the user.

iii. Multiple Semantics

If a website maintains multiple semantics for DNT: 0, it is responsible for associating the proper semantic with a user agent.  If a website cannot determine the semantics associated with a DNT: 0 exception, it may not rely on the exception.

Non-Normative Discussion:

i. Legal Implications

This specification does not take a position on whether the DNT: 0 exception mechanism is sufficient to satisfy any legal requirements.
