The document/literal style. Literal is the only (@use) supported

Although the soap specification supports multiple documents within the soap

service methods defined with a single document parameter. This is done so
that the user can pass individual parameters instead of one, single document.
To support the complete specification, service methods defined with multiple documents
(multiple message parts), must present a I{document} view for that method.
