+// Overview:
+// Test power down and wakeup event notification
+// API Information:
+// Power::PowerDown(), Power::RequestWakeupEventNotification()
+// Details:
+// - Arm a wakeup timer, enable wakeup events, enter standby mode, get woken up.
+// - Test RequestWakeupEventNotification(): arm a timer, request notification,
+// wait for timer to expire, verify event has been notified, issue another 
+// notification request, disable wakeup events, arm another timer, verify 
+// wakeup event has not been notified, cancel the notification request and
+// close the timer.
+// - Verify that a slave process panics because it hasn't and capability.
+// - Confirm the number of open handles and pending requests are as expected.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
