ASN.1 is certainly hierarchical, but not binary (ASN.1 is a datatype
specification language that can be translated to your favourite implementation
What is binary is the encoding rules (called BER or PER) that are associated
with ASN.1. I recommend PER to people looking for compacity and

Thanks so much! The ASN.1 group is currently meeting in Los Angeles to
progress this work.
One advantage in using a standardized solution vs. an ad-hoc one is that it
Information can be found at: http://asn1.elibel.tm.fr/xml/
If there are people interested in these mappings, it would be my pleasure
to receive their comments (to me directly -- please indicate which mapping
you're interested in: ASN.1 -> XML or XML -> ASN.1) and associate them to our
work to make sure that we end up with what people are looking for.
Finally allow me to say again that, even though ITU-T Recommendations and ISO
standards are not usually freely available, ITU-T allows each and every one to
freely download 3 Recommendations from their website (http://www.itu.int).
