I think that this is simply not true. It's like saying that
XML forces you to support arbitrary GI's... which is an ideal,
if impossible task. At the end of the day, *every* application
has application-level constraints on the full capabilities
of the underlying XML system. Use of entities, CDATA sections,
etc. can be handled at that level quite effectively.

I have also written a parser, and I agree that some of the
edge cases are a pain. That said, XML parsers are, and will
be, commodity items. I very seldom even use my parser now.

So let's flip this around, and say that we used SML. Do you
think you'd have a *large* reduction in the number of questions?
How about s-expressions? If the XML syntax is so vastly
unsuited/incomprehensible in the problem domain I
find it hard to believe that a similar syntax would do
much to help, or that there wouldn't be a better basic
syntax to use/
How many of your customers try to use external entities?
