    Description ( 
       "The PolicySetValidityPeriod aggregation represents scheduled "
       "activation and deactivation of a PolicySet. A PolicySet is "
       "considered \"active\" if it is both \"Enabled\" and in a valid "
       "time period. \n"
       "\n"
       "If a PolicySet is associated with multiple policy time periods "
       "via this association, then the Set is in a valid time period "
       "if at least one of the time periods evaluates to TRUE. If a "
       "PolicySet is contained in another PolicySet via the "
       "PolicySetComponent aggregation (e.g., a PolicyRule in a "
       "PolicyGroup), then the contained PolicySet (e.g., PolicyRule) "
       "is in a valid period if at least one of the aggregate\'s "
       "PolicyTimePeriodCondition instances evaluates to TRUE and at "
       "least one of its own PolicyTimePeriodCondition instances also "
       "evalutes to TRUE. (In other words, the "
       "PolicyTimePeriodConditions are ORed to determine whether the "
       "PolicySet is in a valid time period and then ANDed with the "
       "ORed PolicyTimePeriodConditions of each of PolicySet instances "
       "in the PolicySetComponent hierarchy to determine if the "
       "PolicySet is in a valid time period and, if also \"Enabled\", "
       "therefore, active, i.e., the hierachy ANDs the ORed "
       "PolicyTimePeriodConditions of the elements of the hierarchy. \n"
       "\n"
       "A Time Period may be aggregated by multiple PolicySets. A Set "
       "that does not point to a PolicyTimePeriodCondition via this "
       "association, from the point of view of scheduling, is always "
       "in a valid time period." )]
