Ordered   The value ordered can be set for the ordering property of an association end. This signifies that instances of the classifiers at the target end of the association are ordered. Any operation that adds or changes the instances is responsible for maintaining the order. The multiplicity at the target end must be greater than one since a value of one or less would specify a set with one or less elements, for which ordering would be meaningless.

Explanation

The value ordered means that the order of instances of the classifier at the target end (near end) is specified and that any operations on the source (far end) classifier must take responsibility to maintain this order if they add or change instances.

Association End  Base Type An association end is related to the valueordered, which specifies the ordering property, because this attribute is added to an association end to increase the precision of the semantics, describing an aspect of the way the classifier participates in the association relationship.
