The org.apache.xerces.impl.validation.ValidationState you are passing to the
Xerces XSSimpleTypeDecl has a NULL TypeValidatorHelper and the Xerces build
which is XML Schema 1.1 aware looks a lot in the TypeValidatorHelper to see if
it is running in XML Schema 1.1 compatibility mode like:
final String options = context.getTypeValidatorHelper().isXMLSchema11() ?
"Xbh" : "X";
The class org.apache.xerces.impl.dv.xs.XSSimpleTypeDecl is an internal Xerces
class. Maybe you should try breaking dependencies to internal classes.
