I've been messing around with X.680, aka ASN/1. Its reputation for
horrible evilness, I find, primarily comes from the Packed Encoding Rules
and the interface with statically typed languages, both of which require
dealing with the schema language programmatically. But if you want to
drive it from a dynamically typed language, it's dirt simple: to write, see
what data type you have, output a type and length and value (or type and
value and terminator), and there you are.
I've got a little back burner project called Twinjo that provides two
equivalent serialization formats: X.680 and an extensible S-expression
format. If anyone's interested, you can read about it at <
