Extension: Is Selective

Official URL: http://hl7.org/fhir/StructureDefinition/cqf-isSelective Version: 1.0.0-ballot
Standards status: Trial-use Maturity Level: 3 Computable Name: IsSelective

Allows a given data requirement to be identified as “selective”, meaning that it can be used as an additive criteria to filter a population. A selective data requirement is guaranteed to define a subset (not necessarily proper) of the initial population of an artifact. If multiple data requirements are marked selective, they all apply (i.e. AND semantics).
