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

Some external object models do not provide information about ID attributes; in such cases this function will always return an empty sequence. In particular, this is true when the object model is a DOM.
