1. Extension
Definition | The technical possible range of determined values. 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
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.

Type | Extension
Summary | false
Alternate Names | extensions, user content
