| 0. Extension | |
| Definition | R5: Optional Extension Element - found in all resources. |
| Short | R5: subject additional typesOptional Extensions Element |
| Comments | Element In addition, because the subject needs to be resolved during realization, use of subjects in actions (or in the ActivityDefinition referenced by the action) resolves based on the set of subjects supplied in context and by type (i.e. the patient subject would resolve to a resource of type Patient). |
| Control | 0..1* This element is affected by the following invariants: ele-1 |
| Is Modifier | false |
| Invariants | 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())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.url | |
| 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-PlanDefinition.action.subject |
| 4. Extension.value[x] | |
| Definition | A code, group definition, or canonical reference that describes the intended subject of the action and its children, if any. 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 - must be one of a constrained set of the data types (see Extensibility for a list). |
| Short | Type of individual the action is focused onValue of extension |
| Comments | The subject of an action overrides the subject at a parent action or on the root of the PlanDefinition if specified. In addition, because the subject needs to be resolved during realization, use of subjects in actions (or in the ActivityDefinition referenced by the action) resolves based on the set of subjects supplied in context and by type (i.e. the patient subject would resolve to a resource of type Patient). |

| Short | R5: subject additional types |
| Comments | Element In addition, because the subject needs to be resolved during realization, use of subjects in actions (or in the ActivityDefinition referenced by the action) resolves based on the set of subjects supplied in context and by type (i.e. the patient subject would resolve to a resource of type Patient). |
| Control | 0..1 This element is affected by the following invariants: ele-1 |

| 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. |
| Short | Unique id for inter-element referencing |

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