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

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

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

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

This is the same as above, see 
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. 
Those are the tokens (only for cookies) that are transported in the P3P 
Header of the HTTP-answer to the GET request. If you don't use a 
cookie, you won't need the compact format at all. 

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