Topic: Validator: unknown CodeSystems throws error

The java validator and tx.fhir.org are throwing errors when trying to validate codes from an unknown CodeSystem.
This should be a Warning instead.

indeed, it should be a warning. So can you be specific about what you are doing/calling and what the validation response is?

I've also noticed this as well and this example( patient-example.json) throws an error with Unknown Code System http://hl7.org/fhir/v2/0203 when I run java -jar org.hl7.fhir.validator.jar patient-example.json -version 4.0.
Version of the validator is FHIR Validation tool Version 4.1.41-SNAPSHOT (Git# bdab9a78b39a). Built 2019-12-31T14:32:35.701+11:00 (10 days old)
I didn't see a method in ValidationEngine.java similar to setAnyExtensionsAllowed to change these to warnings.
Is there a way to change unknown CodeSystem errors to warnings ? Happy to help find a solution by testing and digging in further.

so that is not a R4 patient, and the error message is correct. If you validate that against R3, there's no error. If you valdiate it against R4, that is correctly an error - Note that it's not an unknown code system, because there's nothing defined in hl7.org/fhir that is not knowable for the validator. So it's an illegal code system
Reece Adamson (Jan 13 2020 at 17:28):
Thanks for the clarification! I can see how it is an illegal code system because the code is included in the extensible ValueSet bound to the profile. I don't think the current "Unknown Code System" error message conveys the actual issue.
Grahame Grieve (Jan 13 2020 at 19:54):
the issue is that the code system itself is not valid.
Reece Adamson (Jan 13 2020 at 20:04):
Gotcha. I misinterpreted your original response, but understand now.
