Re: CCPP and P3P compatibility concerns

Dear Mr. Klyne,

P3P spec WG decided to change the P3P spec, so that generic
URI forms can be used as a P3P data item identifier.

For the details, please see the latest P3P spec.
http://www.w3.org/TR/2000/WD-P3P-20000424/

I hope this change improves the compatibility
between CCPP and P3P.
