SessionDiagnostics contains general diagnostic information about the session; the SessionSecurityDiagnostics Variable contains security-related diagnostic information. Because the information of the second Variable is security-related, it should not be made accessible to all users, but only to authorised users.

SubscriptionDiagnosticsArray is an array of Subscription diagnostic information per opened subscription, as defined in 12.15. Its TypeDefinitionNode is the VariableType SubscriptionDiagnosticsArrayType providing a Variable for each entry in the array, as defined in 7.11.
