Definition

Indicates an authoritative source for performing value set expansions.

Comment:

If the designated "authoritative source" (as specified in the valueset-authoritativeSource extension, if present) is unable to provide a valid expansion, this extension indicates an alternate authoritative source where the value set expansion may be performed. The alternate authoritative source url must reference a FHIR terminology server endpoint (the [base] url of the FHIR server).
