The "EDI folks" are not the drivers of electronic commerce. GM is
partnered with CommerceONE and Ford is partnered with Oracle. The EDI
people are merely falling into line.

LISP S-expressions have three problems:

 * even more stigma than SGML
 * as you say, angle brackets were king
 * no schema language

But yes, if Microsoft had backed s-expressions, XML would not be where
it is today. And nobody would be whining that XML is way too large and
complicated for many applications. That might be a good thing.
DSSSL-style S-expressions would be MUCH better for representing property
relationships than XML is, and property relationships are pretty central
to e-commerce and all sorts of machine to machine communication.

SML people: think on this.
