The “new content” box at http://build.fhir.org/ig/HL7/US-Core/StructureDefinition-us-core-observation-screening-response.html#root states:
  

The following are example usage scenarios for the US Core-Results profile:

• Query for survey screening results for a patient.
• Record or update screening results results belonging to a Patient

… but I don’t see anything called a “US Core-Results profile”, and this page is about SDOH. Is the quoted text copy/pasted from somewhere by accident?
