    006 * An additional interface that can be implemented by the {@link HasAssignmentContext} class.
    007 * The assignment context holder (see {@link AssignmentContextHolder}) can than use this interface
    008 * to store assignment contexts directly on the {@link HasAssignmentContext} class, if the
    009 * assignment permits it (the {@link Assignment#getIndex()} is implemented, i.e., a non negative
    010 * index is returned).
