Range
Overview
See also Examples, Detailed Descriptions, Mappings, Profiles and Extensions
A set of ordered Quantity values defined by a low and high limit.
A Range specifies a set of possible values; usually, one value from the range applies (e.g., "give the patient between 2 and 4 tablets"). Ranges are typically used in instructions.
[%dt Range 5%]
The unit and code/system elements of the low or high elements SHALL match. If the low or high elements are missing, the meaning is that the low or high boundaries are not known and therefore neither is the complete range.
The comparator flag on the low or high elements cannot be present. Note that the Range type should not be used to represent out of range measurements: A quantity type with the comparator element should be used instead.
The low and the high values are inclusive and are assumed to have arbitrarily high precision; e.g., the range 1.5 to 2.5 includes 1.50, and 2.50 but not 1.49 or 2.51.

Elements
- Range.low [0..1]: SimpleQuantity The low limit. The boundary is inclusive.
- Range.high [0..1]: SimpleQuantity The high limit. The boundary is inclusive.
Comments
- Range.low: If the low element is missing, the low boundary is not known.
- Range.high: If the high element is missing, the high boundary is not known.
