Using ICF with FHIR

Hi! I’m trying to figure out how ICF can be used in the FHIR standard. The link http://hl7.org/fhir/sid/icf-nl does not work. Is it possible to use this classifier in FHIR? How to do it?

The URL doesn’t need to resolve. You simply put that URL as the “system” in Coding.system and put your code in Coding.value.
