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: 

You may also look at the PRIME framework:
that tries to do some negotiation.
