* Description:        This class represents the policy information, which has been

*                resolved in some way from the actual WSP. Currently applications

*                typically "just know", which policy WSP prefers, but in the

*                future this class may be used as a container for data

*                originating directly from a WSP (as the for example, when the

*                Liberty ID-WSF evolves).

*                To point out a single feature, lets go through the Identity

*                Provider ID list getter, setter and adder -methods; these are

*                meant to be used as a storing place for a the policy information

*                Typically the IDP ID list is just a recommendation, and rarely

*                a strict list.
