Spring WS 2.1.0. Expose WSDL with external schema.

It is a good practice to keep schema external to your wsdl.
In Spring WS documentation it is not clearly mentioned how to publish wsdl with external schema.
After some time searching google i managed to found the solution:
<!-- WSDL -->
  <sws:static-wsdl id="BookingFacadeService" location="/WEB-INF/wsdl/BookingFacadeService.wsdl"  />
 
<!-- Schema -->
  <bean
        id="BookingFacadeService_schema"
        class="org.springframework.xml.xsd.SimpleXsdSchema">
        <property
            name="xsd"
            value="/WEB-INF/wsdl/BookingFacadeService_schema.xsd">
        </property>
    </bean>

BookingFacadeService.wsdl is my wsdl which include the external schema BookingFacadeService_schema.xsd.
