Our mustSupport rules don't set expectations for display.  We need some.  Specifically:

DTR apps and EHRs that take on DTR app responsibility SHALL be able to render Questionnaires and QuestionnaireResponses.  Specifically, apps and EHRs acting as form fillers SHALL be able to display:

• QR.questionnaire.questionnaireDisplay/Questionnaire.title
• QR.authored
• QR.author.resolve().name
• QR.source.resolve().name
• QR.item.text
• QR.item.value - all data types
• The same for all nested items

They SHALL also handle all mustSupport elements within the Questionnaire profile and provide visual cues where those elements impact expected user action (e.g. required answers, need for signatures, etc.)

Those same systems SHOULD be able to display QR.item.itemMedia
