The ICF (International Classification of Functioning, Disability and Health, https://www.who.int/standards/classifications/international-classification-of-functioning-disability-and-health) has an OID in the HL7 OID Registry 2.16.840.1.113883.6.254

https://www.hl7.org/oid/index.cfm?Comp_OID=2.16.840.1.113883.6.254

…and the symbolic name associated with it is correctly “icf”.

If I hush through the FHIR list of code systems

https://build.fhir.org/terminologies-systems.html

…I see this one

The URI ends up with “icf-nl”. How can that be? Even if William Goossens from the Netherlands is the submitter of the OID request, the ICF is an international classification and thus should have this URL http://hl7.org/fhir/sid/icf-
