+------------------------------------------------------------------------+

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

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

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