One thing to definitely check for is how you are parsing the Schema files. By
default, XMLBeans uses the context classloader to look for types (like in
Factory.parse()). In a std Java app, the context and current classloaders are
the same, but in Ant they are not.
Try this when parsing the Schema:
SchemaTypeLoader loader =
XmlBeans.typeLoaderForClassLoader(SchemaDocument.class.getClassLoader());
loader.parse(...)
