|Description||string||PolicyConditions may be aggregated into rules and into compound conditions. PolicyConditionStructure is the abstract aggregation class for the structuring of policy conditions.
The Conditions aggregated by a PolicyRule or CompoundPolicyCondition are grouped into two levels of lists: either an ORed set of ANDed sets of conditions (DNF, the default) or an ANDed set of ORed sets of conditions (CNF). Individual PolicyConditions in these lists may be negated. The property ConditionListType specifies which of these two grouping schemes applies to a particular PolicyRule or CompoundPolicyCondition instance.
One or more PolicyTimePeriodConditions may be among the conditions associated with a PolicyRule or CompoundPolicyCondition via the PolicyConditionStructure subclass association. In this case, the time periods are simply additional Conditions to be evaluated along with any others that are specified.
