Roy.  I just don't understand what this means. Your point about an open web relying on servers having some flexibility to reject misconfigured headers was well taken.  But isn't the point of any spec to displace semantics? 

Whether a **server** and a **UA** are accurately communicating with each other only depends on whether each knows what signals to send and what actions to take in response. The spec should describe that.

Whether a UA accurately describes to **users** what a **feature** does is a problem we know how to address using messaging and where that fails, legally under misrepresentation.   This group should pass on that.

Please, someone.  Do a find/replace "tracking" with "froobalicious" in the documents.  Make sure all the actors affected by the doc will know what to do in the absence of any reliance on shared semantics about privacy or the meaning of the word tracking.  Even add a sentence to the intro that explicitly states "Tracking means many things to many people and this spec does not attempt to define it.  Instead, it describes a technique for users to express a limited preference for how certain data about them is used, a mechanism for recipients to respect that preference, and exceptions that permit certain business functions to continue even if the preference is activated."

>> For example, if I tell you "on my property, you are required to be froobalicious" you might reasonably ask "what do you mean by froobalicious?".  I might be able to give you a simple definitional answer ('froobalicios means that your socks are always color-coordinated with your tie') but it may be that I hand you a multiple page document that says "froobalicious people must do X, must not do Y, should do Z when Q happens, may do R if an only if T is true, ..." and so on.  That document is as much of a 'definition' of froobalicious as anything else.  It may not be pretty, it may not be terse, it may not be quotable, it may not have a sentence anywhere that says "froobalicious is defined as …" -- but if you abide by my rules, you can say (with pride, I hope) "on Dave's property, I am always froobalicious!" and be confident that you are.
