487 * the same key. Also, the first item under the key contains the entry's own
488 * rdn and the ID of the node's parent, to allow bottom-up tree traversal as
489 * well as top-down. To keep this info first in the list, the nrdnlen is set
490 * to the negative of its value.

493 * directly usable for in-memory manipulation.
