Convert::ASN1by bibliophile (Parson)

bibliophile has asked for the
wisdom of the Perl Monks concerning the following question:
Has anyone here ever worked with the Convert::ASN1 module? I've run into something I don't quite understand....
I'm building a Biblio::ILL::ISO module to handle ISO 10161 interlibrary-loan protocol messages, which uses ASN.1 (and boy was I happy to find Convert::ASN1!).
My problem is with handling ASN.1 extensions (where the ASN.1 description is extended by pointing to other ASN.1 descriptions). Convert::ASN1 does have a mechanism for handling this - at least on the *encoding* side, but I can't seem to get things *decoding* properly (for protocol-based messages that happen to use one of these extensions).
I'm really hoping it's some minor thingy that I'm just not understanding....
Any help you could give would be... well... helpful. :-)
