Why XML instead of ASN.1 or XDR (in the http://RFC.net/rfc1832.html
sense)? All XML really *adds* is that the structure and some comments
(element + attribute names) goes in the file. An ASN.1 encoding that does
that could be easily defined, or the ASN.1 records prefixed with a header
containing some kind of identifier (perhaps a URL to the ASN.1 description
file!) that would allow the debugging tools that came with the ASN.1
toolkit the developer was using to view and hand-edit the records. But XML
as a data format came into the limelight instead, and all this schema
stuff is reinventing the work done on ASN.1 or XDR files... it's all just
part of this industry that people keep reinventing the wheel.

Self describing data formats very similar to XML existed around 1960, I
think - LISP is based on one:

(person
 name: "Alaric Snell"
 age: 40
 addresses: ((email . "alaric@a...")
             (phone . "0845 090 8101")))

...look familiar? :-)

Very little these days is new. Things succeed because vendors hype them,
which happens when the sales department stumbles across the potential of
something - not when that "revolutionary cutting edge technology" was
developed two decades ago :-)

Yeah. My approach to this is to form a small hard core and throw together
a spec right now, without a standards body - like independent RFCs - then
get it Out There so the standards body ends up taking it on.
