# SDC: StructureDefinition-sdc-questionnaire-render-intro

### Scope and Usage

This profile adds additional constraints and extensions to the base [SDC Base Questionnaire Profile](/sdc-structuredefinition-sdc-questionnaire-intro) that support the design of questionnaires with more sophisticated rendering, including tables, specialized controls, styled text, etc. This profile identifies which core elements and extensions must be supported and highlights other elements that, while not required, may be relevant to the questionnaire rendering use-case. Further information on how this use-case is implemented as well as guidance on the elements and extensions included in the profile can be found on the [Advanced Rendering](/sdc-rendering) page.
