This includes identifying which core elements and extensions must be supported. For the purposes of this profile, _Supported_ means that clients SHALL be capable of processing the element/extension and use the information to control the display and information capture associated with the [QuestionnaireResponse]({{site.data.fhir.path}}questionnaireresponse) resource. It means that servers SHALL be capable of persisting those elements and returning them in response to requests. ### Boundaries and Relationships This profile is related to the [SDC Base Questionnaire Profile](/sdc-structuredefinition-sdc-questionnaire-intro) which defines the characteristic of a form "design". This profile focuses on the constraints appropriate to capturing the "answer(s)" to a pre-defined form.
