Resource or profile can be changed after publish it officially. For example, heart rate profile(official URL : http://hl7.org/fhir/StructureDefinition/heartrate)'s fixed code(8867-4) is changed to other text, like 12345-1. Another example, something new resource is created and added to CarePlan resource as reference type.(At the moment, CarePlan resource's maturity level might be increased.) In this case, I think describing version of profile/resource in the content would be a solution.
I thought meta.versionId is the thing, but it has 0...1 text and meta.profile has 0...*. Is there any way to indicate the profile/resource's version?
