    Description

      Eric Haas: using https://cts.nlm.nih.gov/fhir/res/ValueSet/2.16.840.1.113762.1.4.1010.4

      We documented how to access the VSD incorrectly : http://build.fhir.org/ig/HL7/US-Core/terminology.html#using-value-set-authority-center-vsac

      The retrieval of a value set using the FHIR API structure using just the OID provided will only retrieve the value set definition, when available, and to obtain the expansion, the expansion operation is used.

      Eric Haas: will create a tracker to correct
