+-- 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.
