And perhaps I should clarify, the module I'm looking at has:
DEFINITIONS IMPLICIT TAGS ::= BEGIN
in the ASN.1 module for the protocol.
I can confirm that if I specify ASN1_EXP_OPT for the struct implementation,
then everything works, but with the module that I'm looking at having the above
header on the definitions, I don't think that will result in an interoperable
implementation.
Best Regards,
Patrick.
