How CXF/JAXB deal with Xsd:any?

Dear all,
     Please check the xml schema bellow:
     	<xsd:complexType name="OperationType">
		<xsd:sequence>
			<xsd:element name="operationLabel" type="xsd:string" minOccurs="0"/>
			<xsd:element name="operationData" minOccurs="0">
				<xsd:complexType>
					<xsd:sequence>
						<xsd:any namespace="##any" processContents="lax" minOccurs="0"/>
					</xsd:sequence>
				</xsd:complexType>
			</xsd:element>
		</xsd:sequence>
	</xsd:complexType>
        The operationData is xsd:any type. What does it really contain is
controlled by operationLabel.
        So in such scenario, how does cxf deal with the xml message? In
JAXB, any type will be converted to java Object.

Regards

Hubert.

In that case, the generated code would be a JAXBElement<Object>.    What's in 
that object would depend on what is sent on the wire.  If, on the wire, that 
element has an xsi:type attribute with a type that the current JAXBContext 
knows about, the object will be deserialized into the appropriate JAXB 
object.   If jaxb DOESN'T know about it, it will be an DOM.
