[erlang-questions] Re: Optional callbacks

I tried adding

  -optional_callbacks([sample_callback_1/0,
		       sample_callback_2/0,
		       sample_callback_3/0,
		       sample_callback_4/1,
		       sample_callback_5/1,
		       sample_callback_6/3]).

to lib/dialyzer/test/behaviour_SUITE_data/src/sample_behaviour/sample_behaviour.erl, and got the expected Dialyzer messages, so I guess it's more complicated than that. Could you please provide an example?
