The sec-label-basis extension is not based on an existing FHIR artifact, unlike the must-display extension which is based on the Annotation, and the The sec-label-classifier extension which is based on Contributor.

It appears that {{sec-label-basis}}is “based on” an existing FHIR data type: Coding. This paragraph is confusing; might remove this paragraph, or update it to state that this extension use a FHIR Coding rather tha “not absed on an existing FHIR artifact”.
