60 PURPOSE : Decode elements of type nonCriticalExtensions
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 a
64 warning and continue decoding.
65 Whenever a nonCriticalExtensions-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, 10.1.1.1:
71 Information elements applicable to choices reserved for future
72 releases of the protocol shall be added to the end of the message.
73 In future releases non critical informaion elements ... shall
74 be appended at the end of the message.
75 See also 3GPP TS25.921 V4.3.0, 10.4.
