Why the Adaptive questionnaire next question operation is defined on the Questionnaire resource? Wouldn't it make more sence to have it defined on the QuestionnaireResponse resource? I understnad that the idea behind is to get a next question from a questionnaire, but the Questionnaire resource is a definitional stateless resorce, whereas the QuestionnaireResponse resource is a response to an actual, assigned questionnaire. And in adaptive forms we need an actual, assigned questionnaire as the questions are being dynamically developed based on previous answers to questions chosen from an item bank of questions.
