At least one mandatory identifier

[jakubsielewicz]

Currently all identifier slices are optional across all resources which makes it difficult for matching.

It has been suggested by the SMTWG that at least one identifier slice is mandatory across all profiles:

AU PD Healthcare Service AU PD Location AU PD Organisation AU PD Practitioner AU PD Practitioner Role AU PD Secure Messaging Endpoint

However, not being prescriptive on which one it is and publishers can choose.

This was discussed at the HL7AU FHIRWG meeting 25 Oct 2023, and was agreed to be implemented. See minutes https://confluence.hl7.org/display/HAFWG/2023-10-25+FHIRWG+Meeting+Minutes

Note that in order to mandate an identifier for:

• AU PD Practitioner, its related issue #34 must be fixed
• AU PD PractitionerRole, its related issue #35 probably should also be fixed

See #45 - the range of underlying issues with PD identifier definitions will be addressed first before this new feature is implemented

In discussion with @jakubsielewicz and @brettesler-ext to clarify the requirement from the SM technical working group, the requirement is, for a given PD profile to

• mandate at least any one of the known and defined Identifier types
  • eg for AU PD Organisation to mandate any one of AUHPIO, AUPAIOIdentifier, AUCSPRegistrationNumber, AUAustralianBusinessNumber, AUAustralianCompanyNumber, AUAustralianRegisteredBodyNumber, AUNATAAccreditationNumber, AUPharmacyApprovalNumber
• optionally allow any type of local identifier consistent with the core spec Identifier datatype

The PR that implements this change #46 has been merged; therefore this issue can be closed.
