I agree with all your arguments.
These are precisely for such arguments (avoid reinventing the wheel,
embedded devices, high-volume transactions, efficiency, compression ratio,
careful design) that my company (with others) supports what is described at:
http://asn1.elibel.tm.fr/xml/#schema-mapping (I expect some better material as
soon as I can find some time!) and try to benefit from both XML and the
success story with ASN.1 and its associated PER encoding.
