description: Takes a subset of extensions and constraints from the SDC [rendering](http://hl7.org/fhir/uv/sdc/STU3/StructureDefinition-sdc-questionnaire-render.html), [behavior](http://hl7.org/fhir/uv/sdc/STU3/StructureDefinition-sdc-questionnaire-behave.html), and [population](http://hl7.org/fhir/uv/sdc/STU3/StructureDefinition-sdc-questionnaire-pop-exp.html) profiles, reflecting agreed expectations around which data elements might be relevant as well as which must be supported for DTR purposes.
