Yes, but what did we learn from the experience? That external schemas are
quite difficult to deploy and evolve in the real world ... That parsing
data with markup is much easier and more robust than parsing data
against an external schema ... That the type systems of the programming
languages in widespread use are so diverse that it is very difficult
to define a neutral data interchange method that doesn't lose
information yet is simple enough to use by ordinary programmers ...
