If the position is "before" or "after", an index will be chosen which makes
the given node the previous or next node of the given reference node.
If the position "last" is specified, an index higher than any existing index
will be chosen.
If no free index is available between two nodes (for "before" and "after"),
the whole index of the current node level will be renumbered.
