### Messages

Information | StructureDefinition.short | Values for short differ: 'Extension' vs 'Additional content defined by implementations'
Information | StructureDefinition.definition | Values for definition differ: 'An Extension' vs 'May be used to represent additional information that is not part of the basic definition of the resource. 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.'
Information | Encounter.reasonCode | Example/preferred bindings differ at Encounter.reasonCode using binding from AUCoreEncounter
