The MarhsallingView uses a XML Marshaller defined in the org.springframework.oxm package to render the response content as XML. The object to be marshalled can be set explicitly using MarhsallingView's modelKey bean property. Alternatively, the view will iterate over all model properties marhsall only those types that are supported by the Marshaller. For more information on the functionality in the org.springframework.oxm package refer to the chapter Marshalling XML using O/X Mappers.
