This is a question being asked to 'users_at_jaxb.java.net'.
Is there any way to let JAXB properly prints|xmlns:xsi|and|xsi:nill|on
nillable|_at_XmlRootElement|?
|public class XmlValueTest {
public static void main(final String[] args) throws JAXBException {
final JAXBContext context=
JAXBContext.newInstance(Wrapper.class, Value.class);
final Marshaller marshaller= context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
marshaller.marshal(Value.newInstance(null), System.out);
marshaller.marshal(Value.newInstance("null"), System.out);
marshaller.marshal(Wrapper.newInstance(null), System.out);
marshaller.marshal(Wrapper.newInstance("null"), System.out);
}
}

@XmlRootElement
