+
+  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.
