Diagram dedicated to subprocesses. A sub process can be collapsed, in that case, a separated SubProcessDiagram is created. If it is expanded, then the elements are drawn within the subprocess inside the process-collaboration diagram. SubProcess Diagrams contain a subset of the elements that supports a collaboration-process diagram: in particular, elements specific to collaboration, such as message flow, participants, pools and lanes are not presented in SubProcessDiagrams.
