/**
 * Represents additional data to be added to EPRs
 * created from {@link StatefulWebServiceManager} (for advanced users).
 *
 * 
 * Occasionally it is convenient to be able to control the data to be
 * present on {@link EndpointReference}s created by {@link StatefulWebServiceManager}.
 * You can do so by using this class like this:
 *
 * 
 * statefulWebServiceManager.export({@link W3CEndpointReference}.class,myObject,
 *   new EPRRecipe().addReferenceParameter({@link Headers}.create(...))
 *                  .addReferenceParameter({@link Headers}.create(...)));
 * 
 *
 * 
 * The methods on this class follows 
 * the fluent interface design to allow construction without using a variable.
 *
 *
 * 

 * See 
 * WS-Addressing EPR information model for more details.
