Relation MAXIMUM-VALUE-CARDINALITY

Maximum value cardinality is a constraint on the number of values to which a binary relation can map a domain instance. It restrict the relation to AT MOST N values for a given a domain instance. A cardinality of 0 means that the relation does not hold for that instance.
