ASN ERROR and OPERATION

[Casper]

Dear All,

With the help of book of Olivier Duboisson at:
http://asn1.elibel.tm.fr/en/book/index.htm, I managed to finally notice that
the ASN error occurs when it tries to handle ERROR and OPERATION types.

Where is it wrong? Is it the ASN syntax in GSM MAP specification or the
Erlang ASN compiler doesn't know how to handle those 2 types? Or is that
syntax an out dated or very new one?

Thanks!
Eranga
