PAS constraints on the Timing datatype used in the various service requests.

Mandatory Data Elements

The following data elements must always be present.

Each PAS Timing SHALL have at least one of: conf§prof-1

  1. count (with optional countMax)
  2. frequency and period and periodUnit (with optional frequencyMax and periodMax)
  3. calendarPattern extension
  4. deliveryPattern extension

!

Please see the documentation on the FHIR Timing datatype for more information of how common timing uses are represented.
