Note that in the Javadoc a lot of different process are mentioned. The following list will clarify the different meanings.

• Process element: Can be any element which describes a process in BPMN. So, in the most cases it can be a process or sub process
• TProcess: The BPMN element of a process
• TSubProcess: The BPMN element of a sub process
