+
+  PURPOSE : Decoding of the GSM Type CSN1 SHL OPT element. 
+            This coding type enhances the GSM Type CSN1 SHL. It supports 
+            previous behaviour of CSN1_SHL and the lack of the whole 
+            element.
+            The coding type CSN1_SHL_OPT is suitable for elements which 
+            structures match to the following common definition:
+            { null | L | H { 0 | 1 < value part > }
+            
+            The element value can be present, then it is preceded by the 
+            flag value H. If the element is represented by the flag L only 
+            the value is absent! Besides the absence of the whole element 
+            is allowed.

+
+  PURPOSE : Encoding of the GSM Type CSN1 SHL OPT element doesn't differ
+            from encoding of the GSM Type CSN1 SHL. 
+            This element consists of a 1 bit valid flag and a value part. 
+            If the element is valid (the v_xxx components is TRUE in the
+            decoded message) a H bit will be coded followed by the
+            coding of the value part. Otherwise a L bit will be
+            coded.
