  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.
