A parameter provides a means of communication with operations and other BehavioralFeatures. A parameter passes or communicates values of its defined type.

Attributes
Class	direction	This attribute specifies the purpose of the parameter; to input a value, to output a value, both purposes, or to provide an operation return value.
Class	multiplicity	Multiplicity defines cardinality constraints on the set of instances or values that a Parameter can hold. Multiplicity defines a lower and upper bound on the set, although the upper bound can be specified as Unbounded.
