0. Extension
Definition	R4B: `EvidenceReport.subject` (new:BackboneElement) Optional Extension Element - found in all resources.
Short	R4B: Focus of the report (new)Optional Extensions Element
Comments	Element `EvidenceReport.subject` is not mapped to FHIR STU3, since FHIR R4B `EvidenceReport` is not mapped. Element `EvidenceReport.subject` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). While the source element matches Basic element path `(`), the definitions are not compatible (source: `BackboneElement`:1..1 -> basic: `Reference(http://hl7.org/fhir/StructureDefinition/Resource)`:0..1). May be used as an expression for search queries and search results
Control	10..1* 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.
