| 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. |

| 84. Extension.extension:imageRegion3D.extension:regionType.id | |
| Definition | unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | xml:id (or equivalent in JSON) |
| Control | 0..1 |
| Type | string |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
| XML Format | In the XML format, this property is represented as an attribute. |
| 86. Extension.extension:imageRegion3D.extension:regionType.extension | |
| Definition | 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 | Additional 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. |
