-/// This protocol provides the services required to implement the Boot Service
-/// SetWatchdogTimer(). It provides a service to set the amount of time to wait
-/// before firing the watchdog timer, and it also provides a service to register
-/// a handler that is invoked when the watchdog timer fires. This protocol can
-/// implement the watchdog timer by using the event and timer Boot Services, or
-/// it can make use of custom hardware. When the watchdog timer fires, control
-/// will be passed to a handler if one has been registered. If no handler has
-/// been registered, or the registered handler returns, then the system will be
-/// reset by calling the Runtime Service ResetSystem().
