Xamarin.forms OnPlatfom

Hi i would like to do something like this:

    <StackLayout Padding="15,0">
        <OnPlatform x:TypeArgumets="View">
              <On Platform="iOS">
        <Label Text="ios label" />
      </On>
              <On Platform="Android">
        <Label Text="android label" />
     </On>
        </OnPlatform>
  </StackLayout>

Is there any TypeArguments which allows me to add custom elements for each platform?
thanks
