Does anyone know of papers/books that have a comparison between
ASN.1 and X.409?

Thanks.

A comparision is not directly sensible.
ASN.1 is an extended version of X.409.
The brief way of getting the gist of the differences is to read the tables
of APPLICATION tags in both standards and see what was added to make ASN.1

So, if something was legal in X.409, it should be legal ASN.1 too (unless
they fixed some bugs in the spec - they probably did :-)
