XPath 4.0 Functions and Operators
Saxon availability
Available in XPath 4.0, XSLT 4.0, and XQuery 4.0. Requires Saxon-PE or Saxon-EE. Implemented since Saxon 12. Available for all platforms.
Notes on the Saxon implementation
Available since Saxon 13 in XPath 4.0. Available since Saxon 12.0 provided that syntax extensions are enabled.
The Saxon implementation always evaluates the $input argument eagerly,
making it useful to force evaluation of an expression that has side-effects.
