Use the decision-state element as an alternative to the action-state to make a routing decision using a convenient if/else syntax. The example below shows the moreAnswersNeeded state above now implemented as a decision state instead of an action-state:

<decision-state id="moreAnswersNeeded">
    <if test="interview.moreAnswersNeeded()" then="answerQuestions" else="finish" />
</decision-state>
