for any or all of the built-in scopes. For example, a third-party web 
 application framework might provide a conversation context object for 
 the built-in conversation scope.</p>
 
 <p>The context associated with a built-in scope propagates across 
 local, synchronous Java method calls, including invocation of EJB 
 local business methods. The context does not propagate across remote 
 method invocations or to asynchronous processes such as JMS message 
 listeners or EJB timer service timeouts.</p>
