Name	Flags	Card.	Type	Description & Constraints
DV_AMOUNT	C	0..*	DV_QUANTIFIED	This is an abstract type. Child types: DV_COUNT, DV_DURATION, DV_QUANTITY Abstract class defining the concept of relative quantified 'amounts'. Elements defined in Ancestors:CR, LF, Local_terminology_id, normal_status, normal_range, other_reference_ranges, magnitude_status, accuracy Constraints: Accuracy_is_percent_validity, Accuracy_validity
accuracy_is_percent		0..1	boolean	If `True`, indicates that when this object was created, `_accuracy_` was recorded as a percent value; if `False`, as an absolute quantity value.
accuracy		0..1	decimal	Accuracy of measurement, expressed either as a half-range percent value (`_accuracy_is_percent_` = `True`) or a half-range quantity.
