Notes on the Saxon implementation

Available as defined in XSLT 3.0 since Saxon 9.6, replacing the previously available function map:for-each-entry (which was available since Saxon 9.4). Available in XSLT, XPath, and XQuery, whether or not 3.0 is available.

XPath 3.1 version implemented since Saxon 9.7.

Saxon always compares string-valued keys using the Unicode codepoint collation.
