    Determines whether this variable is supposed to be a local variable in case of concurrency in its scope. This affects
    - tree expansion (not evaluated yet by the engine)
    - activity instance IDs of variable instances: concurrentLocal variables always receive the activity instance id of their execution (which may not be the scope execution), while non-concurrentLocal variables always receive the activity instance id of their scope (which is set in the parent execution)
    In the future, this field could be used for restoring the variable distribution when the tree is expanded/compacted multiple times. On expansion, the goal would be to keep concurrentLocal variables always with their concurrent replacing executions while non-concurrentLocal variables stay in the scope execution
