unfortunately, I'm considering it as generic and abstract.
I think we have no need to model a specific type of power
controller, because what we are doing is to construct a 
power controlling process, not to realize a hardware platform's
device for special purpose.
Yes, you can say not all devices are happy to do with power
management, but I would say, I'm not going to force every
devices to do that.
