for a override method, a inherited feature could reduce the code and maintenance of the notify properties of super's method
for example. in a base class. it notifies
@Command @NotifyChange(

{"message","items","selected"}

)
public void delete(){}

the subclass how extends it and override delete :
@Command @NotifyChange(

{"message","items","selected","mynotify"}

)
public void delete()

{super.delete();//}

if it could assign inherited = ture, then the code become :
@Command @NotifyChange({"mynotify"},inherited=true)
public void delete(){super.delete();//}
