Currently I’m working on converting object to XML, I notice all object properties are listed as XML elements (node) unless you use @XmlAttribute on a particular getter or setting

Just wondering is there a way to automatically convert all object properties as XML attributes in JAXB.

Sample Code: 

JAXBContext jc = JAXBContext.newInstance( foo.class );
Marshaller m = jc.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
m.setProperty(Marshaller.JAXB_FRAGMENT, true);
Foo foo = new foo();
foo.setType("type");
foo.setValue("value");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
m.marshal(foo, baos);

    Note: I’m the EclipseLink JAXB (MOXy) lead and a member of the JAXB (JSR-222) expert group.

    There currently isn’t a way to configure that by default simple properties should map to XML attributes. The following enhancement request has been filed for MOXy to add this behaviour.
