If it is passed more than once, it sets a preference list where the order of appearance signifies descending priority. For example, passing 4, 2, 3 creates the preference list (CCID-4, CCID-2, CCID-3), assigning CCID-4 highest preference. The request is reconciled with the CCIDs on the server through the 'server-priority' mechanism of RFC 4340 6.3.1/10. The server CCIDs can be listed by calling 'para_client si'. "
