## 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).

### Structure

Name | Flags | Card. | Type | Description & Constraints Filter: Bindings Constraints Obligations
--- | --- | --- | --- | ---
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
