I was using the asn1bean Java library yesterday funnily enough. I'm sure it's fine for X.509 stuff, however lucky me got to use it with the more obscure parts of X.400. It's lacking support for COMPONENTS OF, and a bunch of other things that were likely deprecated from the ASN.1 spec a few decades ago.

Any luck with it?

I need something like this.
