Heheh, any XML folk who thinks that this is an asset of XML haven't read:

http://www.w3.org/TR/REC-xml#charencoding

"processors are, of course, not required to support all IANA-registered 
encodings"

Again, for anybody who has approached XML in the search for a single 
concrete syntax but not come across this point yet, I recommend XDR... 
or to just be pragmatic and say "My decoder will only read XML in one of 
the charsets XML1.0 requires me to accept" or, equivelantly, "My decoder 
will only read BER" and then stop making spurious and libelous claims 
about ASN.1 encodings being less interoperable than XML character sets :-)
