## Intersection of http://hl7.org/fhir/uv/ips/StructureDefinition/Quantity-uv-ips and http://hl7.org/fhir/uv/ips/StructureDefinition/Quantity-uv-ips

This is the set of resources that conform to both Quantity (IPS) (http://hl7.org/fhir/uv/ips/StructureDefinition/Quantity-uv-ips) and Quantity (IPS) (http://hl7.org/fhir/uv/ips/StructureDefinition/Quantity-uv-ips).

--- | --- | --- | --- | ---
Quantity | C | 0..* |  | A measured amount using UCUM 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
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
