Class Range
This data type represents a set of possible values between a low value and a high value. The values are quantities, which may include a unit of measure. The unit of measure is typically going to be the same in the low value and the high value (e.g., 2 years  5 years, but not necessarily so (e.g., 6 months  3 years). The low and high values are inclusive (e.g., 2  4 tablets allows 2, 3, or 4 tablets).
This class was called PhysicalQuantityInterval in the past, in alignment with HL7 V3, but was renamed to Range to align with FHIR. Note that this class used to have four properties: lowValue, lowUnit, highValue, and highUnit, the values being reals and the units being codes. This was similar to the V3 PhysicalQuantityInterval. This has been changed to a low and high, both of type quantity, which is equivalent.
"A set of ordered Quantity values defined by a low and high limit."  HL7 FHIR, Range
This data type represents an Interval, where the Low and High Limits are Physical Quantities. An Interval is a "set of consecutive values of an ordered base data type."  HL7 V3. A Physical Quantity is "a dimensioned quantity expressing the result of measuring"  HL7 V3
Attributes 
«PQ» Quantity  high 
"The high limit. The boundary is inclusive."  HL7 FHIR, Range.high "The high limit of the interval. The high limit SHALL NOT be negative infinity, and SHALL be higher than the low limit if one exists."  HL7 V3. This property contains the numeric portion (i.e., not including any units of measure) of the high limit. "The high limit of the interval. The high limit SHALL NOT be negative infinity, and SHALL be higher than the low limit if one exists."  HL7 V3. This property contains the Unit of Measure of the high limit.

«PQ» Quantity  low 
"The low limit. The boundary is inclusive."  HL7 FHIR, Range.low "The low limit of the interval. The low limit SHALL NOT be positive infinity."  HL7 V3 This property contains the numeric portion (i.e., not including any units of measure) of the low limit. "The low limit of the interval. The low limit SHALL NOT be positive infinity."  HL7 V3. This property containsthe Unit of Measure of the low limit.
