Context of Use: Use on Element ID Questionnaire.item or Element ID ElementDefinition, with Context Invariant = type='quantity'
A set of units that the user may choose when providing a quantity value.
Comment:
Provide either unitOption(s) or unitValueSet. If either of the extensions are present, the units for a Quantity element are constrained to only the units listed by the extensions - i.e. it is treated as a "required", not an "extensible" binding. In the absence of either, any unit is valid. See additional guidance and examples in the SDC implementation guide. If this extension present and an answer is provided for the question item in the QuestionnaireResponse, then the valueQuantity SHALL have a Quantity.code and Quantity.system that match the Coding.code and system of one of the allowed values if the Coding has a code and/or system. If the Coding only has a display, then the Quantity.unit must match. (Note that Coding with only a display is strongly discouraged.) If there is a match on code and system, but no match on display/unit, systems MAY raise a warning. However, because of translation and bandwidth considerations, some systems MAY opt to drop the unit or express it in an alternate language. Validation of the Quantity unit MAY be performed by using the $validateCode operation, populating the elements passed into the operation from the Quantity.code, system and unit elements.
