Hi Adrian,
Unfortunately, the ASN.1 compiler does not support the X.681 spec (Information Class Objects).
So, regarding your final question, I am afraid that our ASN.1 compiler cannot compile the X.509 standards without major enhancements.
Kind regards,
George Mamais

That's great, thanks.

The official ITU-T X.509 ASN.1 specification found at [1] (under "Formal
description(s)") does not use the problematic construct (ANY DEFINED BY). The compilation still fails with the following error:
$ mono asn1.exe -Ada AuthenticationFramework.asn File AuthenticationFramework.asn, line 52:24 no viable alternative at character '&'
It seems that the TYPE-IDENTIFIER information object class (specified in X.681, [2]) is not supported by asn1scc.
Is there a way to work around this issue or do you think compiling the
X.509 specs requires enhancements to the asn1scc tool?
Thanks again for you help.
Best regards,
Adrian
