Show additional info in $validate response

[atuonufure]

Problem I need to solve

As a response to operation /FHIR/<resourceType>/$validate we can get information about the invalid resource structure, e.g.:

resourceType: OperationOutcome
text:
  status: generated
  div: Invalid resource
issue:
  - severity: fatal
    code: invalid
    expression:
      - Questionnaire.launchContext
    diagnostics: Expected type of 'vector, got 'persistentarraymap
  - severity: fatal
    code: invalid
    expression:
      - Questionnaire.item.1.itemHidden
    diagnostics: unknown key :itemHidden

Unfortunately, we can't detect what exactly the zen profile caused this error.

Solution I see

Example response:

  - severity: fatal
    code: invalid
    expression:
      - Questionnaire.item.1.itemHidden
    diagnostics: unknown key :itemHidden
    profiles: 
      - hl7-fhir-uv-sdc.sdc-questionnaire
      - hl7-fhir-uv-sdc.sdc-questionnaire-extr-defn
