| -- Humble attempt of extracting the common part of RUA, HNBAP and RANAP out of |
| -- their respective ASN.1 syntax definitions. Hidden in all those information |
| -- object classes is a quite classic 'message header' structure that is identical |
| -- to all of the messages of the above protocols. Only the actual information element |
| -- contents is specified as 'real' ASN.1 complex data type. |
