/**
 * This interface defines the plug-point that is responsible for creating a
 * proxy for an AsyncHandler instance provided by a client
 * application as part of an async request invocation. This interface allows the
 * plug-in implementor to create a proxy which wraps the client-provided
 * AsyncHandler instance and can be used to perform
 * application-server-specific actions in conjunction with the execution of the
 * AsyncHandler instance, such as thread context migration, etc.
 * 
 * To use this plug-point, you must define a class which implements this
 * interface, then register your implementation with the JAX-WS
 * FactoryRegistry.setFactory() method.
