0. Extension
Definition	R5: `Timing.repeat.when` Optional Extension Element - found in all resources.
Short	R5: whenOptional Extensions Element
Comments	Element `Timing.repeat.when` is mapped to FHIR R4 element `Timing.repeat.when` as `SourceIsBroaderThanTarget`. When more than one event is listed, the event is tied to the union of the specified events.
Control	0..* 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.
Control	1..1
Type	uri
Is Modifier	false
XML Format	In the XML format, this property is represented as an attribute.
Summary	false
Fixed Value	`http://hl7.org/fhir/5.0/StructureDefinition/extension-Timing.repeat.when`
4. Extension.value[x]
Definition	An approximate time period during the day, potentially linked to an event of daily living that indicates when the action should occur. Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
Short	Code for time period of occurrenceValue of extension
Comments	When more than one event is listed, the event is tied to the union of the specified events.
Control	0..1
Binding	The codes SHALL be taken from For codes, see R5EventTimingForR4 (0.1.0) (required to `http://hl7.org/fhir/uv/xver/ValueSet/R5-event-timing-for-R4\|0.1.0`) Real-world event relating to the schedule.

Short	Unique id for inter-element referencing
Control	0..1
Type	string
Is Modifier	false
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.
Control	0..*
Type	Extension
Is Modifier	false
Summary	false
Alternate Names	extensions, user content
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()`)
Slicing	This element introduces a set of slices on `Extension.extension`. The slices areUnordered and Open, and can be differentiated using the following discriminators: value @ url
6. Extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
