For example, a measure may reference a value set defining possible age ranges, rather than (and potentially in addition to) embedding the calculation of the age ranges into measure logic. See the MeasureStratifierAgeRangeExample value set for an example. If present, the value set SHALL be consistent with the criteria (i.e., the criteria, when evaluated, will result in values from the value set)."/>
