Parse issue with namespaces in web.xml

When parsing the following web.xml (that used to work on AS 6)

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name>ServletTestClient</display-name>
<servlet>
<servlet-name>ServletTestClient</servlet-name>
<servlet-class>org.jboss.test.ws.jaxws.jbws3140.ServletTestClient</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ServletTestClient</servlet-name>
<url-pattern>/ServletTest</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>60</session-timeout>
</session-config>

<service-ref>
<service-ref-name>service/mtomTest</service-ref-name>
<service-interface>org.jboss.test.ws.jaxws.jbws3140.EndpointService</service-interface>
<service-ref-type>org.jboss.test.ws.jaxws.jbws3140.MTOMTest</service-ref-type>
<wsdl-file>WEB-INF/wsdl/TestEndpoint.wsdl</wsdl-file>
<service-qname xmlns:servicens="http://TestEndpoint.org">servicens:TestEndpointService</service-qname>
<port-component-ref>
<service-endpoint-interface>org.jboss.test.ws.jaxws.jbws3140.MTOMTest</service-endpoint-interface>
<enable-mtom>true</enable-mtom>
<mtom-threshold>750</mtom-threshold>
<addressing>
<enabled>true</enabled>
<responses>ANONYMOUS</responses>
</addressing>
</port-component-ref>
</service-ref>
</web-app>

I get a parsing exception:
