## Intersection of http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-datatype-timing and http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-datatype-timing

This is the set of resources that conform to both PAS Timing (http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-datatype-timing) and PAS Timing (http://hl7.org/fhir/us/davinci-pas/StructureDefinition/profile-datatype-timing).

--- | --- | --- | --- | ---
Timing |  | 0..* |  | A timing schedule that specifies an event that may occur multiple times
extension |  | 0..* | Extension | Additional content defined by implementations
modifierExtension | ?!Σ | 0..* | Extension | Extensions that cannot be ignored even if unrecognized
event | Σ | 0..* | dateTime | When the event occurs
repeat | Σ C | 0..1 | Element | When the event is to occur Constraints: tim-1, tim-2, tim-4, tim-5, tim-6, tim-7, tim-8, tim-9, tim-10
