Extension ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1 Constraints- ele-1: All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count()) - ext-1: Must have either extensions or value[x], not both
extension.exists() != value.exists()

| extension | C | 0..* | Extension | There are no (further) constraints on this element Element idExtension.extension Short descriptionAdditional content defined by implementations Alternate namesextensions, user content DefinitionMay be used to represent additional information that is not part of the basic definition of the element. 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 can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
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.
