60 PURPOSE : Decode elements of type criticalExtensions
61
62 An element of this type should never be encoded or decoded.
63 If the coder faces an IE of this type, it should report an
64 error report and abort.
65 Whenever a criticalExtensions-IE is extended from NULL or
66 SEQUENCE {} to another type, its CCD coding type will change
67 and the functions in this file will not be called for that IE
68 any more.
69
70 According to 3GPP TS25.331 V3.6.0, 10.1.1.2.2:
71 Since messages including critical extensions are rejected by
72 receivers not comprehending them, these messages can be
73 modified completely, e.g. IEs may be inserted at any place
74 and IEs may be removed or redefined.
75 See also 3GPP TS25.921 V4.3.0, 10.4.
