Given this example:

{{}}

<vaccineCode>
  <extension
    url="http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-notDoneValueSet">
    <valueCanonical
       value="http://cts.nlm.nih.gov/fhir-r3/ValueSet/2.16.840.1.113883.3.464.1003.196.11.1220"/>
  </extension>
  <text value="Influenza, seasonal, injectable, preservative free"/>
</vaccineCode>

{{}}The problem is that the text doesn't match the extension both structurally and detail

{{}}

The text is the concept, but the concept is not a concept, it's a value set. And the text is for the first concept in the value set, not the set of things the value set describes.

{{}}

And so the rendering of the concept in the IG publisher, and any other system, isn't a correct statement of what's going on, and I don't think it's clinically safe

{{}}

And nor did the IG explain to me in any meaningfully way how I would use that extension to say something clinically meaningful, and nor did I find resolving the value set reference in the example at all straight forward

{{}}

Please make sure the use of this extension is clearly implementable in a safe way.

Grahame Grieve: but we need to get this thing done. Can the committee take this up as a future work item and make sure that's clearly implementable in a safe way in the fut
