org.xml.sax.SAXException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'post-handler-chains'

Issue

• A Web Service is consumed by .Net based dynamic proxy client, which required to configure it to use '.NET friendly Endpoint' in web.xml.
• How to combine two JBossWS endpoint configs together here ?
• The client only supports WS-Security which requires to use 'Standard WSSecurity Endpoint' as provided below:

<endpoint-config>
    <config-name>.NET friendly with Example</config-name>
    <feature></feature>
     <post-handler-chains>
      <javaee:handler-chain>
        <javaee:protocol-bindings>##SOAP11_HTTP ##SOAP11_HTTP_MTOM</javaee:protocol-bindings>
        <javaee:handler>
          <javaee:handler-name>WSSecurity Handler</javaee:handler-name>
          <javaee:handler-class>org.jboss.ws.extensions.security.jaxws.WSSecurityHandlerServer</javaee:handler-class>
        </javaee:handler>
        <javaee:handler>
          <javaee:handler-name>Recording Handler</javaee:handler-name>
          <javaee:handler-class>org.jboss.wsf.framework.invocation.RecordingServerHandler</javaee:handler-class>
        </javaee:handler>
      </javaee:handler-chain>
    </post-handler-chains>
  </endpoint-config>

• Is it possible to use the handler-chain for security and endpoint config for .net friendly WSDL generation?

@HandlerChain(file = "ws-security-handler-chain.xml")

• The error that is encountered while trying to combine two JBossWS configs is:

Caused by: org.xml.sax.SAXException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'post-handler-chains'. One of '{"urn:jboss:jaxws-config:2.0":feature, "urn:jboss:jaxws-config:2.0":property}' is expected. @ *unknown*[84,27]
