Guidance on how to interpret the contents of this table can be found here.
| 1. Extension | |
| Definition | Timeout in seconds to attempt notification delivery. Optional Extension Element - found in all resources. | 
| 2. Extension.extension | |

| 4. Extension.value[x] | |
| Definition | If present, the maximum amount of time a server will allow before failing a notification attempt. Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |

| 1. Extension | |
| Definition | Timeout in seconds to attempt notification delivery. 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 unless an empty Parameters resource (: hasValue() or (children().count() > id.count()) or $this is Parameters) 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. | 
| Control | 0..0* | 
| Type | Extension | 
| Summary | false | 
| Alternate Names | extensions, user content | 
| 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. | 
| 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()) | 
| Slicing | This element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators: 
 | 
| 3. Extension.url | |
| Definition | Source of the definition for the extension code - a logical name or a URL. | 
| Control | 1..1 | 
| Type | uri | 
| XML Representation | In the XML format, this property is represented as an attribute. | 
| Summary | false | 
| 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/uv/subscriptions-backport/StructureDefinition/backport-timeout | 
| 4. Extension.value[x] | |
| Definition | If present, the maximum amount of time a server will allow before failing a notification attempt. Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). | 
| Control | 0..1 |
