47   * will access the shared memory space created by the Kernel to extract the
48   * current status of the running Service. Using a simple XSL file it will
49   * finally produce the final ExecuteResponse including the updated
50   * percentCompleted attribute of the ProcessStarted node of the cached
51   * document if any (so if the Service is currently running) else it will
52   * return the final ExecuteResponse stored on the Server file system.
