64 PURPOSE : Decoding of the GSM Type CSN1 SHL OPT element.
65 This coding type enhances the GSM Type CSN1 SHL. It supports
66 previous behaviour of CSN1_SHL and the lack of the whole
67 element.
68 The coding type CSN1_SHL_OPT is suitable for elements which
69 structures match to the following common definition:
70 { null | L | H { 0 | 1 < value part > }
71
72 The element value can be present, then it is preceded by the
73 flag value H. If the element is represented by the flag L only
74 the value is absent! Besides the absence of the whole element
75 is allowed.

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