25   * Simple marker object which represents an actual snapshot of version scoped conversational data.
26   * It can be referred in the version scoped managed-bean for a later rollback to an expected state.
27   * <p/>
28   * Alternatively it takes a name to identify the snapshot later on. In this case no reference has to be
29   * maintained in the managed-bean which may be somewhat more convenient.
30   * <p/>
31   * Conversational beans usually may be of large size and therefore not suited for handling in the
32   * managed-bean directly. A SavePoint therefore only represents a placeholder for conversational data
33   * without any direct reference to it.
