Hello,
Format of the encoded value should be as follows in BER
TLV // T-Tag, L-Length, V-Value
E.g.
X SEQUENCE ::= {
xx INTEGER, -- say xx = 05
yy BOOL OPTIONAL,...} -- say yy = true
the above may be encoded as
0x30 0x06 0x02 0x01 0x05 0x01 0x01 0xFF
T L T L V T L V
T L ( -----------V-------------)
again the value can be nested ! Can you be more clear what is T ? TV?
Warm regards,
Vasa

Hi,
With BER encoding, would it be possible to take care of T, TV ...
representations ?
Thanks
