    Example
    MarkAndUnmarkAsErrors
    // Get all the errors due to features violating the "PointProperlyInsideArea" topology rule.
    
    using (TopologyDefinition topologyDefinition = topology.GetDefinition())

      foreach (TopologyError error in errorsDueToViolatingPointProperlyInsideAreaRule)
      {
        topology.MarkAsException(error);

      // Now verify all the errors from features violating the 'PointProperlyInsideArea' topology rule have indeed been
      // marked as exceptions.
      //
      // By default, ErrorDescription is initialized to ErrorType.ErrorAndException.  Here we want ErrorType.ErrorOnly.
    
      errorDescription = new ErrorDescription(topology.GetExtent())

      Console.WriteLine($"There are {errorsAfterMarkedAsExceptions.Count} feature violating the 'PointProperlyInsideArea' topology rule after all the errors have been marked as exceptions.");
    
      // Finally, reset all the exceptions as errors by unmarking them as exceptions.
    
      foreach (TopologyError error in errorsDueToViolatingPointProperlyInsideAreaRule)
      {
