To do what you are trying to do with Apache SOAP, you would need to
write a serializer for Element. As you have experienced, Apache SOAP
lets you [de-]serialize an Element through its custom literal XML
encoding. When using literal XML, you can only [de-]serialize
Element. For standard SOAP encoding, there is no Element serializer.
The standard workarounds are to use either (1) the XML as a string or
(2) Java classes appropriate for your problem domain, instead of
Element.
