Extension: StructureDefinition Dependent Profiles

FHIR Infrastructure Work Group

Maturity Level: 1

Trial Use

Use Context: Any

Official URL: `http://hl7.org/fhir/StructureDefinition/structuredefinition-dependencies`				Version: 5.0.0-snapshot3
draft as of 2014-01-31				Computable Name: SDDependencies
Flags: Non-Modifier				OID: 2.16.840.1.113883.4.642.5.1038

Context of Use: Use on Element ID StructureDefinition

Definition

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.

Constraints

ele-1: All FHIR elements must have a @value or children (xpath: hasValue() or (children().count() > id.count()))

ele-1: On Extension.extension: All FHIR elements must have a @value or children (xpath on Extension.extension: hasValue() or (children().count() > id.count()))
ext-1: On Extension.extension: Must have either extensions or value[x], not both (xpath on Extension.extension: extension.exists() != value.exists())
ele-1: On Extension.value[x]: All FHIR elements must have a @value or children (xpath on Extension.value[x]: hasValue() or (children().count() > id.count()))
