AT:

• There exists a variableListener extension element that can be declared on BPMN scopes (i.e. tasks, embedded subprocesses, processes, etc.)
• Variable listeners semantics are the same as for the CMMN implementation

Hints:

• Think about how variable listeners can work with asynchronous continuations. For example, when a process is started asynchronously, we fire the historic events AFTER the async continuation. The same should probably be possible with the variable events.
