Error when marshaling wps LiteralValue

Getting this error when marshaling WPS 2.0 LiteralValue objects:
> Instance of "net.opengis.wps.v_2_0.LiteralValue" is substituting "net.opengis.ows.v_2_0.ValueType", but "net.opengis.wps.v_2_0.LiteralValue" is bound to an anonymous type.. Instance of "net.opengis.wps.v_2_0.LiteralValue" is substituting "net.opengis.ows.v_2_0.ValueType", but "net.opengis.wps.v_2_0.LiteralValue" is bound to an anonymous type..

Looking at the generated code for LiteralValue it has a @XmlType(name = "") which is causing the issue and seems to be coming from the nested complexType.

Start by inspecting the generated WPS 2.0 LiteralValue class and the source schema's nested complexType. Reproduce marshaling of a LiteralValue and trace how its anonymous @XmlType binding is generated. Done means the object marshals without the reported substitution error and the generated binding is corrected.
