That's an amazingly ambitious library, thanks for the reference!
Unfortunately code that works directly from schema documents is usually
wrong, at least in the sense that it cannot process arbitrary valid
schemas. For example, the following restriction is documented, and rules
out many real schemas:
"The constraint of this algorithm is that a local element is not allowed
to be declared with the same name of a global element."
