|Representation Options||UML Representation:
Collaboration or CollaborationInstanceSet, stereotyped as <<use-case realization>>.
Use-case realizations express the behavior of a set of model elements performing some or all of an Artifact: Use Case. As a result, there should be a use-case
realization for each use case which needs to be expressed in the design model. Similarly, if use cases are not used,
then use-case realizations will also be omitted.
