Hi Boris,
Unfortunately I wasn't able to create a simple case which would match
the complexity of the x3d schema. What I did was remove the majority of
the unused elements and types from the x3d schema. I hope this is ok -
if not let me know and I will try to create something more to your
liking.

Included is a tarball (bzip2) containing README, Makefile, driver.cxx,
x3d-3.0.xsd (reduced), and test.x3d.

Let me know if you need anything else.

Thanks,
Pat
