http://hl7.org/fhir/StructureDefinition/targetConstraint|5.2.0

Specifies a constraint that is enforced on instantiated (or target) resources. This extension can be applied to definitional resources (such as ActivityDefinition or Measure) and indicates that the constraint should be enforced on resources that are instantiated from the definition. For example, this extension can be used to define a constraint such as `numerator count must be less than or equal to denominator count`.
