XML Marshalling
The MarshallingView uses an XML Marshaller (defined in the org.springframework.oxm
package) to render the response content as XML. You can explicitly set the object to be
marshalled by using a MarshallingView instance’s modelKey bean property. Alternatively,
the view iterates over all model properties and marshals the first type that is supported
by the Marshaller. For more information on the functionality in the
org.springframework.oxm package, see Marshalling XML using O/X Mappers.
