Behavioral or Structural?

[sbaldrick]

A use case is a behavioral component of UML - agreed?

A use case diagram .. is a structural component of UML?

A use case diagram shows no concept of events or actions ocurring over time. It justs shows a structured decomposition of fucntionality into use cases - hmmm?

Currently the use case diagram is classed as behavioral in EA. I think it should be structural.

So kind!

It's UML that classifies use case diagrams as behavioral. FWIW, I agree. UseCase is a BehavioredClassifier which is a classifier that can define behavior specifications in its namespace. Although use cases have structure, it's the behaviors that they own that are more interesting.
