It is in so far related as the idea of attaching policy information to 
the exchange is kept, but the vectorial direction of the information 
carried by the tag is returned by 180 degrees.

Whether they will be ignored or not, is a decision by the implementer. 
And NO, this is not at all harmful in the sense that Ian Hickson 
described. I have understood the remarks differently. Ian Hickson may 
clarify. Because this would mean that you and others would consider 
P3P harmful to browsers and exposing users to risks. I have heard a 
lot of things about P3P, but not that it exposes users to higher

You're missing the point, as interoperability would require that the 
UA as a decision point has some information about the applicable 
policy and where to find it before sending the location data. This 
sort of requirement typically is part of an API. My element would tell 
how to bind a P3P Policy to a location data request to the UA. (Or 
start a negotiation process in PRIME or PrimeLife)

Referring to the Website UI just means: "gimme the 25 pages of 
legalese per request". This isn't my goal and as such is not a 
desirable outcome. I think you still put me in another drawer that (as 
I said) is orthogonal. The requirements TLR is talking about are 
different and directly affecting the API. Here it is just a URI field 
with meaning "reserved for policy". I think I could provide a wording 
for the Spec..

And only because you (or your understanding of the majority of user 
agents) don't want to implement it, doesn't mean that others won't 
make a plugin/Extension using exactly that option (see e.g. Prime). My 
suggested tag would be the opener for the world of policy without 
affecting the API for those not willing to care for privacy at all. 

It may be nice if Richard Barnes could comment.
