Having an element called "description" of type "int" does sound fishy to me, so I suggest you change that to "string".
I seem to vaguely remember that there is a Schema rule according to which you can't remove an element by restriction and then in a subsequent derivation step, add it back by extension, which is what is happening here. If my recollection is correct, then there is a bug in XMLBeans for not catching this error sooner. If not, then it is just a Java limitation (are you compiling with jdk1.5 or 1.4?)
