 * A disjunct union node is the inverse of a {@link UnionNode}. It evaluates to true only iff all its
 * children are false. Conversely, it evaluates to false if any of its children are true.
 *
 * As an RS query it looks like {@code -(@f1:v1|@f2:v2)}
 *
 * @see DisjunctNode which evaluates to true if any of its children are false.
