SHALL$getIdentifierList

Request for a list of identifiers (across source systems) for a particular Client.

SHALL$linkClients

This operation is used to link two Clients. Linking is an internal procedure where the system applies some confirmation and 'links' resource instances with an internal mechanism. The 'link' is not disclosed or part of any FHIR resource, but a user can confirm the linkage by searching with the identifier list operation.
