The idea behind P3P is to have a standard computer readable format for 
web site privacy policies. The text you refer to is the human-readable 
translation of the computer-readable code. The whole point of P3P is to 
have standardized policies that a computer can read. There are some 
fields such as "consequence" that allow people to provide free form 
text, but mostly it is expected that you will use your full 
human-readable policy for detailed explanations (in addition to your 
P3P policy).
