This was a bug: in some cases, the facet-violation was not channelled
back to the main validation function.

Fixed in CVS, xmlschemas.c rev 1.133.
I added your case to the regression tests.

We have currently no informative error-messages for union types. So
you'll get only a "The character content is not valid." message.

Thanks for the report!
