| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Short | identifies the meaning of the extension |
| Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |

| 4. Extension.value[x] | |
| Definition | If true or a reference, indicates the resource is an example instance. If a reference is present, indicates that the example is an example of the specified profile. Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |

| Comments | Typically, conformance resources and knowledge resources are directly part of the implementation guide, with their normal meaning, and patient linked resources are usually examples. However this is not always true. |

| 2. Extension.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |

| Summary | false |
| 4. Extension.extension | |
| Definition | 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 managable, 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. |
| 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. |

| Slicing | This element introduces a set of slices on Extension.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators: |
