61 PURPOSE : Decoding of the non-standard type CSN1 S0 element.
62 The encoding rule for this type is very similar to the
63 CSN.1 type. Except for the presence flag which is 0 in
64 this case.
65 The encoded IE consists of one bit for presence flag and
66 a value part. Only if the flag bit is equal 0 the value
67 part will follow it.

91 PURPOSE : Encoding of the non-standard type CSN1 S0 element.
92 The encoding rule for this type is very similar to CSN.1
93 type. Except for the presence flag which is 0 in this
94 case. The encoded bit pattern consists of a 0 bit as
95 valid flag and a value part. If the element is present
96 (the v_xxx component is TRUE in the decoded message)
97 a 0 bit will be coded followed by the encoded value part.
98 Otherwise a 1 bit will be encoded.
99 Possible array types are given by melem[e_ref].repType:
100 0) ' ' => {0| IE} (no array)
101 1) 'i' => {0 IE} ** 1 (many repeations up to a 1 bit)
102 2) 'v' => {0|1 IE}* val (val is another IE)
103 3) 'c' => {0|1 IE}* 3 (3 is an example)
