Support country code for Kosovo

[samuel-colin-foph]

The IG requires any country code to come from one of these sets (reference: CH Core Address - CH Core (R4) v5.0.0 ):

• Valueset-iso3166-1-2 - FHIR v5.0.0
• Valueset-iso3166-1-3 - FHIR v5.0.0

Apparently, Kosovo does not have an ISO3166-1-2 code, but XK is used frequently, eg. by the European Commision and the IMF (see ISO 3166-1 alpha-2 - Wikipedia).

Given the links between Switzerland and Kosovo, there is a need for a code. What would be a clean way to add one? Add an additional ValueSet?

CH Core https://fhir.ch/ig/ch-core/StructureDefinition-ch-core-patient.html is limiting with the rule pat-3 the country codes to Valueset-iso3166-1-2 - FHIR v5.0.0
Valueset-iso3166-1-3 - FHIR v5.0.0

see https://fhir.ch/ig/ch-core/StructureDefinition-ch-core-patient.html.

this rule should be probably reduced to a warning, it seems too strict, but this will need a new version of CH Core

@oliveregger Last time, you mentioned that the country check specifically may be deactivated in the validator until the issue is properly fixed. Do we already have an idea if it is feasible?

[oliveregger]

@samuel-colin-foph no this rule be deactivated at the moment easily, this feature would need to be added in a future version and seems not easy to integrate

We discussed it internally and decided to wait for the upstream fix instead of using a temporary fix like a custom extension. Do we need to take further action here or will this be solved automatically in a few months?
