// The HwModeSelect class is intended to serve as a base class for other
// classes that are then used to select a value based on the HW mode.
// It contains a list of HW modes, and a derived class should provide a
// list of corresponding values.
// These two lists must have the same size. Make sure that a violation of
// this requirement is diagnosed.
