description: This profile is derived from the [US Core QuestionnaireResponse Profile](https://hl7.org/fhir/us/core/STU6.1/StructureDefinition-us-core-questionnaireresponse.html) profile and enforces the various elements of [signature](https://hl7.org/fhir/us/davinci-cdex/signatures.html) documented in the CDex guide to represent an enveloped signature. It adds the following constraints:\n- The signature extensions use the CDex Signature Profile
