Hello, here is draft language for the compliance document on user agent requirements. The first paragraph is new, the second two are copied-and-pasted from Section 3 of the current TPE spec. Replace 4.2 Intermediary Compliance (empty) with this new section: 4.2 User Agent Compliance A user agent MAY offer a control to express a tracking preference to third parties. The control MUST communicate the user's preference in accordance with the [[Tracking Preference Expression (DNT)]] recommendation and otherwise comply with that recommendation. A user agent MUST NOT express a tracking preference for a user unless the user has interacted with the user agent in such a way as to indicate a tracking preference. We do not specify how tracking preference choices are offered to the user or how the preference is enabled: each implementation is responsible for determining the user experience by which a tracking preference is enabled. For example, a user might select a check-box in their user agent's configuration, install an extension or add-on that is specifically designed to add a tracking preference expression, or make a choice for privacy that then implicitly includes a tracking preference (e.g., "Privacy settings: high"). Likewise, a user might install or configure a proxy to add the expression to their own outgoing requests. Although some controlled network environments, such as public access terminals or managed corporate intranets, might impose restrictions on the use or configuration of installed user agents, such that a user might only have access to user agents with a predetermined preference enabled, the user is at least able to choose whether to make use of those user agents. In contrast, if a user brings their own Web-enabled device to a library or cafe with wireless Internet access, the expectation will be that their chosen user agent and personal preferences regarding Web site behavior will not be altered by the network environment, aside from blanket limitations on what resources can or cannot be accessed through that network. Implementations of HTTP that are not under control of the user /must not/ express a tracking preference on their behalf. -- Justin Brookman Director, Consumer Privacy Center for Democracy& Technology 1634 I Street NW, Suite 1100 Washington, DC 20006 tel 202.407.8812 fax 202.637.0969 justin@cdt.org http://www.cdt.org @CenDemTech @JustinBrookman
