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.
68
69 The element value can be present, then it is preceded by the
70 flag value 0. If the element is represented by the flag 1 only
71 the value is absent! Besides the absence of the whole element
72 is allowed.

96 PURPOSE : Encoding of the non-standard type CSN1 S0 element.
97 The encoding rule for this type is very similar to CSN.1
98 type. Except for the presence flag which is 0 in this
99 case. The encoded bit pattern consists of a 0 bit as
100 valid flag and a value part. If the element is present
101 (the v_xxx component is TRUE in the decoded message)
102 a 0 bit will be coded followed by the encoded value part.
103 Otherwise a 1 bit will be encoded.
104 Possible array types are given by melem[e_ref].repType:
105 0) ' ' => {0| IE} (no array)
106 1) 'i' => {0 IE} ** 1 (many repeations up to a 1 bit)
107 2) 'v' => {0|1 IE}* val (val is another IE)
108 3) 'c' => {0|1 IE}* 3 (3 is an example)
