  PURPOSE : Decode elements of type criticalExtensions

            An element of this type should never be encoded or decoded.
            If the coder faces an IE of this type, it should report an
            error report and abort.
            Whenever a criticalExtensions-IE is extended from NULL or 
            SEQUENCE {} to another type, its CCD coding type will change
            and the functions in this file will not be called for that IE
            any more.

            According to 3GPP TS25.331 V3.6.0, 10.1.1.2.2:
            Since messages including critical extensions are rejected by 
            receivers not comprehending them, these messages can be 
            modified completely, e.g. IEs may be inserted at any place 
            and IEs may be removed or redefined.
            See also 3GPP TS25.921 V4.3.0, 10.4.
