1. Extension
Definition	FHIR IG Optional Extension Element - found in all resources.
Control	0..* This element is affected by the following invariants: ele-1
Invariants	Defined on this element 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())
2. Extension.extension:ig-publication
SliceName	ig-publication
Definition	An Extension May 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.
Control	0..1*
Type	Extension
Summary	false
Alternate Names	extensions, user content
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.
Invariants	Defined on this element 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())
