This structure is derived from Quantity
| Name | Card. | Type | Constraints and Usage |
|---|---|---|---|
 Quantity | 0..* | Quantity | qty-3: If a code for the unit is present, the system SHALL also be present Definition: A measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies. Comments: Usage Note: Quantity profile is mimicking Duration profile. |
 value | 1..1 | decimal | Definition: The value of the measured amount. The value includes an implicit precision in the presentation of the value. Comments: The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books). |
| system | 1..1 | uri | Definition: The identification of the system that provides the coded form of the unit. |
 code | 1..1 | code | Definition: A unit of time (units from UCUM). Comments: The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system. |
