  <description value="Validate that a coded value is in the set of codes allowed by a value set.   If the operation    is not called at the instance level, one of the in parameters &quot;identifier&quot; or    &quot;valueset&quot; must be provided.  One (and only one) of the in parameters (code,    coding, codeableConcept) must be provided.  The operation returns a result (true / false),    an error message, and the recommended display for the code" />
