## Intersection of http://hl7.org/fhir/StructureDefinition/SimpleQuantity and http://hl7.org/fhir/StructureDefinition/SimpleQuantity

This is the set of resources that conform to both SimpleQuantity (http://hl7.org/fhir/StructureDefinition/SimpleQuantity) and SimpleQuantity (http://hl7.org/fhir/StructureDefinition/SimpleQuantity).

### Structure

Name | Flags | Card. | Type | Description & Constraints Filter: Bindings Constraints Obligations
--- | --- | --- | --- | ---
Quantity | C | 0..* |  | A fixed quantity (no comparator) ele-1: All FHIR elements must have a @value or children qty-3: If a code for the unit is present, the system SHALL also be present sqty-1: The comparator is not used on a SimpleQuantity
extension |  | 0..* | Extension | Additional content defined by implementations ele-1: All FHIR elements must have a @value or children ext-1: Must have either extensions or value[x], not both
value | Σ | 0..1 | decimal | Numerical value (with implicit precision) ele-1: All FHIR elements must have a @value or children
unit | Σ | 0..1 | string | Unit representation ele-1: All FHIR elements must have a @value or children
