Resource Profile: DTR Questionnaire for adaptive form

The DTR Adaptive Questionnaire is used to represent an adaptive Questionnaire when actually filling out a QuestionnaireResponse. NOTE: This profile does not realistically need the questionnaireAdaptive extension, but will remain intact due to potential impacts on Structured Data Capture (SDC) requirements. (Efforts will be made in an attempt to get the SDC requirements on this extension loosened in a future release)

Usages:

• Use this Profile: DTR Questionnaire Response for adaptive form
• Refer to this Profile: DTR Metric Data
