Hi Richard, 

and here is Lorrie's answer: 

really worth reading. And I agree with her  answer to the claim that the P3P 
compact format is "impractical": "It's not obvious to me there's any 
fundamental reason why a proper P3P compact policy wouldn't work in that 

In the work on DNT I constantly see the desperate need for simple notification 
of the user coming up. And people there constantly re-invent P3P with other 
angle brackets. So claiming P3P is outdated is IMHO a self-serving 
declaration. P3P is not widespread anymore and we may re-invent it in some 
other ways. Because whoever asks for "Transparency:  Consumers have a right to 
easily understandable information about privacy and security practices." will 
have to look at P3P as it provides exactly that.
(see http://www.whitehouse.gov/the-press-office/2012/02/23/we-can-t-wait-
obama-administration-unveils-blueprint-privacy-bill-rights for that last 

But I also think it's clear that we won't take up P3P as is. How to re-invent 
P3P? Dave Raggett had made a nice suggestion:

This merits further discussion IMHO
