| 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. |

| Fixed Value | http://hl7.org/fhir/5.0/StructureDefinition/extension-ActivityDefinition.subject |
| 4. Extension.value[x] | |
| Definition | A code, group definition, or canonical reference that describes or identifies the intended subject of the activity being defined. Canonical references are allowed to support the definition of protocols for drug and substance quality specifications, and is allowed to reference a MedicinalProductDefinition, SubstanceDefinition, AdministrableProductDefinition, ManufacturedItemDefinition, or PackagedProductDefinition resource. Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
| Short | Type of individual the activity definition is intended forValue of extension |
| Comments | Note that the choice of canonical for the subject element was introduced in R4B to support pharmaceutical quality use cases. To ensure as much backwards-compatibility as possible, it is recommended to only use the new canonical type with these use cases. |

| XML Format | In the XML format, this property is represented as an attribute. |
| 4. Extension.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. |
