// This is a mix-in class which handles the enabling policy for
// CButtonEnabler.
//
// For an object to be enabled by a CButtonEnabler attachment, it should
// mix-in and implement this interface. Note that a default policy is
// implemented by CButtonEnabler. This is intended for LControl-derived
// objects which cannot be changed to mix-in MButtonEnablerPolicy and for
// which the default policy in CButtonEnabler already Does The Right Thing<6E>.
