Re: Policy Negotiation

Ashok, 

P3P had exactly the same issue as there was no feedback channel to 
tell why the matching had failed. This was mainly annoying for the 
server side. IBM wrote a paper on how to create a feedback channel 
and presented it on WWW10 in Hongkong. Despite some search I did not 
find it but perhaps Tony can give us the pointer. 
Furthermore, look at the P3P Workshop in Kiel: 
http://www.w3.org/2003/p3p-ws/

You may also look at the PRIME framework:
https://www.prime-project.eu/prime_products/reports/fmwk/
that tries to do some negotiation.

Best, 

Rigo
