Now that we're providing custom namespace handlers (see Spring's NamespaceHandlerSupport) for configuring namespace to default bean mapping, we need to make sure the resolution is reliable. This implies providing a custom namespace handler resolver when parsing the jboss-cxf.xml descriptor.
Moreover, we need to simplify the declaration of namespaces mapping in the spring.handler descriptor in jbossws-cxf-client.jar, as there's overlapping with what's defined in the specific spring.handler descriptors included in CXF component jars.
