RegisterApplication is used to register a new Application Instance with a GlobalDiscoveryServer.
This Method shall be called from an authenticated SecureChannel and from a Client that has access to the DiscoveryAdmin Role or the ApplicationAdmin Privilege (see 6.2).
Servers that support transparent redundancy shall register as a single application and pass the DiscoveryUrls for all available instances and/or network paths.
Servers that support non-transparent redundancy shall register as different applications. In addition, OPC 10000-4 requires the use of the NTRS ServerCapability defined in Annex D.
RegisterApplication shall not create duplicate records if the ApplicationUri already exists.
If RegisterApplication succeeds the OPC UA Application is approved and is returned by QueryApplications and FindApplications.
If registration was successful and auditing is supported, the GDS shall generate the ApplicationRegistrationChanged AuditEventType (see 6.6.12).
