/**
 * This feature clarifies the use of the <code>wsdl:binding</code>
 * in a JAX-WS runtime.
 * <p>
 * This feature is only useful with web services that have an
 * associated WSDL. Enabling this feature requires that a JAX-WS
 * implementation inspect the <code>wsdl:binding</code> for an
 * endpoint at runtime to make sure that all <code>wsdl:extensions</code>
 * that have the <code>required</code> attribute set to <code>true</code>
 * are understood and are being used.
 * <p>
 * The following describes the affects of this feature with respect
 * to be enabled or disabled:
 * <ul>
 *  <li> ENABLED: In this Mode, a JAX-WS runtime MUST assure that all
 *  required <code>wsdl:binding</code> extensions are either understood
    and used by the runtime, or explicitly disabled by the web service
 *  application.  A web service application can disable a particular 
 *  extension that has a known WebServiceFeature using either the appropriate 
 *  annotation associated with that WebServiceFeature on the server, or one of 
 *  the following methods on the client:
 *    <ul>
 *      <li>{@link Service#getPort(QName,Class,WebServiceFeature...)}
 *      <li>{@link Service#getPort(Class,WebServiceFeature...)}
 *      <li>{@link Service#getPort(EndpointReference,Class,WebServiceFeature...)}
 *      <li>{@link Service#createDispatch(QName,Class,Service.Mode mode,WebServiceFeature...)}
 *      <li>{@link Service#createDispatch(EndpointReference,Class,Service.Mode,WebServiceFeature...)}
 *      <li>{@link Service#createDispatch(QName,JAXBContext,Service.Mode,WebServiceFeature...)}
 *      <li>{@link Service#createDispatch(EndpointReference,JAXBContext,Service.Mode,WebServiceFeature...)}
 *      <li>{@link EndpointReference#getPort(Class,WebServiceFeature...)}
 *      <li>One of the <code>getXXXPort(WebServiceFeatures...)</code> methods on a
 *          generated <code>Service</code>.
 *    </ul>
 *  The runtime MUST also make sure that binding of 
 *  SEI parameters/return values respect the <code>wsdl:binding</code>.
 *  With this feature enabled, if a required (<code>wsdl:required="true"</code>)
 *  <code>wsdl:binding</code> extension is in the WSDL and it is not
 *  supported by a JAX-WS runtime and it has not 
 *  been explicitly turned off by the web service developer, then
 *  that JAX-WS runtime MUST behave appropriately based on whether it is 
 *  on the client or server:
 *  <UL>
 *    <li>Client: runtime MUST throw a 
 *  <code>WebServiceException</code> no sooner than when one of the methods
 *  above is invoked but no later than the first invocation of an endpoint
 *  operation. 
 *    <li>Server: throw a WebServiceException and the endpoint MUST fail to deploy
 *  </ul>
 *  <li> DISABLED: In this Mode, an implementation may choose whether
 *  to inspect the <code>wsdl:binding<code> or not and to what degree
 *  the <code>wsdl:binding</code> will be inspected.  For example,
 *  one implementation may choose to behave as if this feature is enabled,
 *  another implementation may only choose to verify the SEI's 
 *  parameter/return type bindings.
 * </ul>
