/**
 * The <code>WebServiceRef annotation is used to
 * define a reference to a web service and
 * (optionally) an injection target for it.
 * It can be used to inject both service and proxy
 * instances. These injected references are not thread safe.
 * If the references are accessed by multiple threads,
 * usual synchronization techinques can be used to
 * support multiple threads.
 *
 * <p>
 * Web service references are resources in the Java EE 5 sense.
 * The annotations (for example, {@link Addressing}) annotated with
 * meta-annotation {@link WebServiceFeatureAnnotation}
 * can be used in conjunction with <code>WebServiceRef.
 * The created reference MUST be configured with annotation's web service
 * feature.
 *
 * <p>
 * For example, in the code below, the injected
 * <code>StockQuoteProvider proxy MUST
 * have WS-Addressing enabled as specifed by the
 * {@link Addressing}
 * annotation.
 *
 * <pre>
 *    public class MyClient {
 *       @Addressing
 *       @WebServiceRef(StockQuoteService.class)
 *       private StockQuoteProvider stockQuoteProvider;
