SDC: StructureDefinition-sdc-questionnaire-itemExtractionContext-intro

Note: This extension has been superceded by the definitionExtract extension. Please migrate to that extension, however this one will remain for backward compatibility.
This extension does not support defining a profile to create, and the expression (x-fhir-query) was not deemed sufficiently implementable.

Additional details on the use of this extension can be found on the Data Extraction page.
