XPath 3.1 Functions and Operators
Saxon availability
Available in XPath 2.0, XSLT 2.0, XQuery 1.0, and later versions. Available in all Saxon editions.

The current Saxon implementation returns the values in "order of first appearance", but it cannot be assumed that this will always remain the case.
