D.4.1.1 Formal Views of Profile Content

The official URL for this profile is: 

http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/cqfm-populationBasis

The population basis specifies the type of elements in the population. For a subject-based measure, this would be boolean (because the population criteria define yes/no values for each individual subject). For a non-subject-based measure, this would be the type of elements in the population (such as encounters or procedures).

This profile builds on Extension.
