This Observation Profile describes how to capture Question/Answer Pairs from IHE SDC. If the question is Multiselect multiple Observations with the same Question Code should be created. A section should also be represented as a grouping Observation. If the question has a follow up text or number entry field e.g. Other (Specify) the information from the textbox should be stored in the Observation.component.value, and the Observation.component.code should repeat the Observation.value as the sub-question.
