Hi Olivier,
As per your direction, I have subscribed to asn1 mailing list but I am
yet to get a cofirmation of my membership and hence not able to post the
question to asn1 mailing list. Since I needed this information urgently,
I am resending the question that I had sent you earlier. Can you throw
some light on this ?
I have a ASN1 file which has a CONTAINING keyword, but unfortunately the
ASN1 compiler does not support this keyword. My question is, is it
possible to bypass this keyword with a workaround so that I can use my
existing ASN1 compiler ?
My sample ASN1 file looks like this..
SEQUENCE {
a INTEGER
b BIT_STRING (CONTAINING K) OPTIONAL
}
You may safely remove "(CONTAINING K)" from the specification, as shown:
SEQUENCE {
a INTEGER
b BIT STRING OPTIONAL
}
(by the way, it is BIT STRING, not BIT_STRING).
You will have to parse the contents of "b" as appropriately (BER/PER)
encoded K, but it comes later, and is purely up to you, if you ever
need it (read: you don't have to parse it unless you know what it is).
K ::= SEQUENCE {
c INTEGER OPTIONAL,
d SEQUENCE {} OPTIONAL
}
Can you also point me to some useful resources in this regard ?
