  17.    --  Detailed Description 
  18.    --  A specific DDSCondition whose trigger_value is completely under the control of the application. 
  19.    --  The DDS.GuardCondition provides a way for an application to manually wake up a DDS.WaitSet. 
  20.    --  This is accomplished by attaching the DDS.GuardCondition to the DDS.SWaitSet and then 
  21.    --  setting the trigger_value by means of the DDS.GuardCondition.set_trigger_value operation.
