Looking at the comments, it seem that many people hate ASN.1 and many people like ASN.1 (I am the latter). (I consider BER to be messy and overly complicated, but DER is much better.) (I wrote a implementation of DER (decoding and encoding), although not the schema format (which I have never needed).)

I'm in the camp of I like it, but I also love to complain about things (see: my inability to say "I love D" without also bringing up other faults).
