Does cxf support xsd:any?

[xuhb]

Hi:
    I am using camel 's payload CXF component; Now I want publish a service 
which doesn't constraint any xml schema, and client can post any xml element to 
this webservice; so I define the wsdl which input message's element is xsd:any; 
it looks like:

<wsdl:message name="anyRequest">
  <wsdl:part name="payload" element="xsd:any"/>
</wsdl:message>
wsdl:operation name="AnyPort">
   <wsdl:input message="tns:anyRequest"/>
 </wsdl:operation>

But CXF doesn't support it now;

I wonderring if this usage is valid to webservice  specification? And should 
CXF support it or not?
