Apparently it happens when one creates a namespace-unaware DOM
document. By default XSD always turns namespace support on so
it was never a problem. It also does not seem to be too hard to
make it work for the other case. I've patched the elements.txx
file to first try to use getLocalName and if it returns 0 then
use getTagName for elements and getName for attributes. The
patched version of elements.txx is available here:

Can try it and let me know if it works in your case? If it does then I
will forward-port this patch for the next version.

Thanks for investigating and reporting this.
