  Multiplicity: [0,1]
  
  How are the activities executed in separate subtask(s). This is actually a shortcut for tailoring the sub-activities: it does not apply to the activity itself, but to its children. TODO reconsider.

  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Whether and how is this activity work distribution auto-scaled.
