I don't like my previous wording here and want to correct it.  While it's true that a Seam-managed persistence context corresponds to an instance of  org.jboss.seam.persistence.ManagedPersistenceContext component,  it's not true that an instance of ManagedPersistenceContext is injected into other components when there is an annotation such as @In EntityManager entityManager.   Rather, the ManagedPersistenceContext acts a manager component for an EntityManager;    the method ManagedPersistenceContext.getEntityManager() is annotated with @Unwrap.   It is the return value of the  @Unwrap method that gets injected when a ManagedPersistenceContext component is referenced.
