This concerns the compact policy transported with the P3P header. This=20
generates the errors.=20

This is a typo as the compact token is called TAI and stands for one=20
time tailoring.

http://www.w3.org/TR/P3P/#compact_retention

A statement about the amount of time that data is retained is missing in=20
the compact header (see the URI above)

This is the same as above, see=20
http://www.w3.org/TR/P3P/#compact_recipients

You will need at least one element.

All those things are not in your policy, but in the compact policy.=20
Those are the tokens (only for cookies) that are transported in the P3P=20
Header of the HTTP-answer to the GET request. If you don't use a=20
cookie, you won't need the compact format at all.=20

If you have a simple setup and no cookie, I would suggest that you use=20
the well-known location (/w3c/p3p.xml) for the Policy Reference File=20
and remove the P3P Header from the Web Server configuration.
