-- 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.
