/**
 * This feature clarifies the use of the {@code wsdl:binding}
 * in a JAX-WS runtime.
 *
 * This feature can be used during the creation of SEI proxy, and
 * {@link Dispatch} instances on the client side and {@link Endpoint}
 * instances on the server side. This feature cannot be used for {@link Service}
 * instance creation on the client side.
 * <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} for an
 * endpoint at runtime to make sure that all {@code wsdl:extensions}
 * that have the {@code required} attribute set to {@code true}
 * 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} extensions(including policies) are
 *  either understood and used by the runtime, or explicitly disabled by the
 *  web service application. A web service can disable a particular
 *  extension if there is a corresponding {@link WebServiceFeature} or annotation.
 *  Similarly, a web service client can disable
 *  particular extension using the corresponding {@code WebServiceFeature} while
 *  creating a proxy or Dispatch instance.
 *  The runtime MUST also make sure that binding of
 *  SEI parameters/return values respect the {@code wsdl:binding}.
 *  With this feature enabled, if a required ({@code wsdl:required="true"})
 *  {@code wsdl:binding} 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
 *  {@link WebServiceException} 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 {@link 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} or not and to what degree
 *  the {@code wsdl:binding} 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>
