      The country code should be conveyed using a standard extension http://hl7.org/fhir/StructureDefinition/iso21090-SC-coding add a binding as preferred to the ISO alpha-2 codes

      Country code is specified in FHIR as a string with suggested use of ISO 3166 2 or 3 letter codes. Use of ISO 3166 2 letter codes is recommended

      I propose to add preferred binding of the country element of address to ISO 3166-1 Alpha2.

      • country from "http://hl7.org/fhir/ValueSet/iso3166-1-2" (preferred) or even (required)

      This would strengthen control of the country element content and improve interoperability by limiting duality in coding by alpha2 and alpha3 codes for the same country.

      We should also consider to strengthen the binding to (required).
