D.4.1.1 Formal Views of Profile Content

The official URL for this profile is: 

http://hl7.org/fhir/uv/cpg/StructureDefinition/cpg-featureExpression

Defines formal computational semantics for the feature, combining the inference and assertion expressions. This is typically only required if the feature is of a different type than the profile (e.g. a boolean feature).

This profile builds on Extension.
