Extension: dependencies

FHIR Infrastructure Work Group Maturity Level: 1InformativeUse Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/structuredefinition-dependencies

Status: draft. Extension maintained by: Health Level Seven, Inc. - [WG Name] WG

Instances can only be valid against this StructureDefinition, if they also sucessfully validate against the dependent profile identified in this extension.

Comment:

Ideally, a profile will restate the constraints of it's base profile and all it's dependent profiles, but this can get pretty complicated once slicing enters the picture. Tools SHOULD not assume that this profile includes all the constraints from the dependent profile.

Context of Use: Use on Element ID StructureDefinition
