Topic: Binding rendering with iso21090-SC-coding extension

I'd like to constrain the iso21090-SC-coding without defining a new specialized extension.
I supposed to do that adding a binding constraint.

        <element id="Patient.extension:luogoNascita.valueAddress.city.extension:codiceComune">
            <path value="Patient.extension.valueAddress.city.extension"/>
            <sliceName value="codiceComune"/>
            <short value="Codice Comune"/>
            <type>
                <code value="Extension"/>
                <profile value="http://hl7.org/fhir/StructureDefinition/iso21090-SC-coding"/>
            </type>
            <binding>
                <strength value="preferred"/>
                <valueSet value="http://hl7.it/fhir/ValueSet/istat-comuni"/>
            </binding>
        </element>

The rendering is not what I expected... (no binding shown)

that is : Binding (unbound) (example)

Is it a rendering problem or should i change approach ?

Grahame Grieve (Mar 06 2020 at 20:59):

hmm. the binding belongs on the Extension value not the extension itself?

Giorgio Cangioli (Mar 09 2020 at 08:55):

..not sure I captured your question... :-)

http://hl7.org/fhir/StructureDefinition/iso21090-SC-coding has no binding defined (and this is reasonable being generic)

I tried to define a binding in the profile where this extension is used. (see the XML fragment above)
