I don't have X.680 handy at the moment, but if you check the docs you will
see that SET requires that new extension additions MUST use tags that are
canonically greater than any other existing tag in the SET, so

Hi,
I have a question on SEQUENCE OF tagging.
I have the following ASN.1 BER definition:
MY_DEF DEFINITIONS IMPLICIT TAGS ::=
BEGIN
X ::= [15] SEQUENCE OF Y;
Y ::= SEQUENCE
{
a INTEGER;
b OCTET STRING;
}
END
In the above definition IMPLICIT global tagging is used.

Hi Chandra,
You use 15 for the outer SEQUENCE OF and 0x30 for the
SEQUENCE.
For example, if you had 2 Y's in X, which had the integers 1 and 2,
and an OCTET STRING of length 0 for each of the OCTET STRING, then encoding
in DER would be:
0x9f, 0xe -- My encoding for the
