Detailed description of policies in Policy Manager needed

Is there a detailed description of policies in Policy Manager 6.6 GUI available?

In the Operations Guide or the Online Help I can only find the "Base Installation Actions and their permissions", but this is not very clear.

Customer wants to know, what action is behind of each policy with a use case.

In the Operation Guide on Page 300 I can found an IMPORTANT notice "The only permission that should be changed is the Remote Application ..." Why are the other policies there, if they should not be changed - this is very confusing for the customer?
