       This XML Schema corresponds to the list of Private Identifiers (IMPIs) 
       as specified in the User Configuration. Please refer to the MIB 
       CL-PKTC-EUE-User for more information. The requirements specified in 
       the MIB table are also applicable to the data elements specified 
       in this XML Schema.

       In addition:
       - If 'pktcEUEUsrIMPIClearAllCredentials' is set to a value of 'true', 
       then the eUE MUST clear all the current IMPI entries in the IMPI table
       and add the new entries provided, in any.
       - If 'pktcEUEUsrIMPIClearAllCredentials' is set to a value of 'false', 
         then the eUE MUST modify any existing entries (identified by the 
         IMPIId) and add any new entries to the IMPI table.
