bag
A collection of elements that may have multiple copies of identical elements, as opposed to a set, in which each element must be unique.
Semantics
Bags may be indicated on multiplicity specifications using the uniqueness flag with a value of false. In combination with the ordering flag, modelers may specify unordered sets, ordered sets, unordered bags, and ordered bags. Ordered bags are called sequences or lists. Multiplicity is applicable to attribute values, association ends, parameters, and other elements.
History
Support for bags on multiplicity is new in UML2.
