"Composite Structure Diagram could be used to show:
(1) internal structure of a classifier - internal structure diagram,
(2) classifier interactions with environment through ports,
(3) a behavior of a collaboration - collaboration use diagram.
The term "structure" for this type of diagrams is defined in UML as a composition of interconnected elements, representing run-time instances collaborating over communications links to achieve some common objectives." [uml-diagrams.org/composite-structure-diagrams.html]
