From OGM-465:

• UC-3.1: I want compensate all operations applied so far and abort the processing of the flush cycle
• UC-3.1.1: I want to execute custom compensation actions
  Example:
• UC-3.1.2: I want to execute automatically determined compensation actions (e.g. a delete for an insert, an insert/update to restore the previous state for a delete/update)
  Example:
• UC-4.1: I want to work with different means of error handling, depending on the "business case" I am in; e.g. I might want to ignore an exception at one time but try to compensate previously applied changes at another time (NOTE: are entity types enough as distinguishing criteria, see UC-2.1.1?)
