The Placer ID (SCH-1.1) is used to identify the appointment.
Appointment information is used to populate [[Appointment]] entities

[[Appointment]]
Matched on: [[Appointment.External Data Point ID]] as derived from SCH-1.1
When matched: [[Appointment.Status]] set to DNA. The other details of the appointment are not updated.
When not matched: New [[Appointment]] created (and immediately set to DNA). In this scenario the S26 message will need to conform to the S12 specification to first create the [[Appointment]]. If it does not then PKB will respond with an AR rejection message.
The message structure is the same as an SIU S15; we only need the Placer ID to set the DNA flag.
If the appointment to be flagged as DNA is not known to PKB, then a new appointment will first be created with the provided information, before then being flagged as DNA. To allow the appointment to be created the S26 message will need to include the additional mandatory elements as detailed in the S12 specification.
