Dear Web Services Architecture Working Group,

I would like to bring to your attention the concerns that
the P3P working group has raised previously to the
the xmlp and ws-cg. We have now been told that our
concerns would most appropriately be addressed by
your group. In summary, our concern is that we need
somebody to specify  how a P3P policy can be associated
with a SOAP message. I am forwarding the relevant
messages from our previous conversation on this topic
for more details. Our original concerns are expressed in
http://lists.w3.org/Archives/Public/xmlp-comments/2002Jul/0031.html

We believe that given that web services deployment
efforts are already underway, we need to move forward
with specifying how to use P3P with web services as soon
as possible.  We do not believe this will be a time consuming effort.

Regards,

Lorrie Cranor
P3P Specification Working Group Chair
