This structure is derived from Quantity

NameCard.TypeConstraints and Usage
.  Quantity 0..*Quantityqty-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..1decimalDefinition:
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..1uri​Definition:
The identification of the system that provides the coded form of the unit.


Comments:
Conformance Rule: Quantity.code must align with Binding: x_TimeUnitsOfMeasure (20230710)

..  code 1..1code​Definition:
A computer processable form of the unit in some unit representation system.


Comments:
Conformance Rule: Quantity.code must align with Binding: x_TimeUnitsOfMeasure (20230710)
