  47                            subclass that is used to classify the entity as well as an operation.
  48                            For progress codes, the operation is the current activity.
  49                            For error codes, it is the exception.For debug codes,it is not defined at this time.

  52                            pairing. The instance differentiates between them. An instance of 0 indicates
  53                            that instance information is unavailable, not meaningful, or not relevant.
  54                            Valid instance numbers start with 1.

  57                            different callers.
