I understand that a call activity can call a process - and that process can be defined as a BPMN process in its own right, and referenced by the call activity.
The BPMN spec says that a call activity can call an atomic “global task” - but is says nothing about how that task is defined, or where information about it is stored, or how it is referenced.
So my question is, how is a global task defined? And what does a call activity calling a global task reference? Or does it just reference a label that is defined and understood by the enterprise (eg - “put on Micky Mouse ears” for the Disney Corp!)?
Thanks very much for any enlightenment!
