Usage of the Enrichment extension

[LucChatty]

Hello,
While browsing the different available options, I found out about the Enrichment option.
I was wondering about what does it add compared to the definition field ?

for example, wouldn't "extension":[{"url":"http://ehelse.no/fhir/StructureDefinition/sdf-fhirpath","valueString":"Patient.name.where(use = 'official').family"}] simply be "definition":"http://hl7.org/fhir/StructureDefinition/Patient#Patient.name.where(use = 'official').family" ?

Best,

Luc

Hey @LucChatty, I have not looked into Questionnaire.item.definition, and I am unsure if it the value after # is FhirPath or something else.

We decided to use FhirPath as per the SDC specification: http://build.fhir.org/ig/HL7/sdc/StructureDefinition-sdc-questionnaire-initialExpression.html

For some reason we created our own extension back then (STU3), probably because we could not find the sdc-questionnaire-initialExpression.
