| 4 | -- their respective ASN.1 syntax definitions. Hidden in all those information |
| 5 | -- object classes is a quite classic 'message header' structure that is identical |
| 6 | -- to all of the messages of the above protocols. Only the actual information element |
| 7 | -- contents is specified as 'real' ASN.1 complex data type. |
