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."
