Definition	R4B: `PlanDefinition.relatedArtifact` additional types (RelatedArtifact) additional types from child elements (citation, display, document, label, resource, type, url) Optional Extension Element - found in all resources.
Short	R4B: Additional documentation, citations additional typesOptional Extensions Element
Comments	Element `PlanDefinition.relatedArtifact` is mapped to FHIR STU3 element `PlanDefinition.relatedArtifact` as `SourceIsBroaderThanTarget`. The mappings for `PlanDefinition.relatedArtifact` do not cover the following types: RelatedArtifact. The mappings for `PlanDefinition.relatedArtifact` do not cover the following types based on type expansion: citation, display, document, label, resource, type, url. Each related artifact is either an attachment, or a reference to another resource, but not both.
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() \| (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) ele-1: All FHIR elements must have a @value or children (hasValue() \| (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short	ExtensionAdditional Content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
