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.

Notes on the Saxon implementation

Saxon effectively executes the doc() function and returns true if it succeeded; as a side-effect, the document will be available in memory for use when the doc() function is subsequently called with this URI.

A user-supplied URIResolver is invoked in the same way as for the doc() function.
