Available in XPath 2.0, XSLT 2.0, XQuery 1.0, and later versions. Available in all Saxon editions.
Notes on the Saxon implementation
The Saxon implementation currently returns the input sequence unchanged, except where the expression used as the argument navigates a reverse axis (for example the ancestor or preceding-sibling axis), in which case the presence of the function causes the nodes to be returned in document order rather than reverse document order.
