Ordinal extension not supported in contained Valueset when using compose but works on expansion

[nielmdrec]

If the Questionnaire contains a Valueset that uses the ordinal extension within an expansion, then the SMART forms renderer is able to display it without issues.

However, if the same extension is used within a compose, the valueset causes this error:

_There was an error fetching options from the terminology server_

Details:

1. the extension in question is:
   http://hl7.org/fhir/StructureDefinition/ordinalValue
2. This is an example that works (using expansion):
   {
   "resourceType":"ValueSet",
   "id":"Mobility",
   "name":"Mobility",
   "title":"MobilityScore",
   "status":"draft",
   "description":"Mobility Score",
   "expansion":{
   "timestamp":"2023-09-01T11:16:50+10:00",
   "contains":[
   {
   "extension":[
   {
   "url":"http://hl7.org/fhir/StructureDefinition/ordinalValue",
   "valueDecimal":0
   }
   ],
   "system":"http://fhir.medirecords.com/CodeSystem/Mobility",
   "code":"0",
   "display":"Complete Independence and Modified Independence - may use any aid, e.g. walking stick"
   }
   ...

AFAIK, the $expand operation typically only looks at Valueset.expansion as the expansion result. Ideally, the ordinalValue extension should be included in Valueset.expansion, not the other way around (renderer looking in ValueSet.compose.include).

There is some discussion here on Zulip:
https://chat.fhir.org/#narrow/stream/179202-terminology/topic/ordinalValue.20extension
https://chat.fhir.org/#narrow/stream/179202-terminology/topic/.24expand.20with.20extensions

I'm still not sure what's the best workaround for this, perhaps we can do as you suggested at the moment. But I might wait for a bit more updates from Brian before proceeding.

Please let me know if it's a blocker.

Thanks, Sean. This is not a blocker for us. As you mentioned, there is a workaround for this.
