Namespace: http://www.w3.org/2005/xpath-functions/map

Applies to: XSLT 3.0 only (if enabled in Saxon: requires Saxon-PE or Saxon-EE)

Notes on the Saxon implementation

Available since Saxon 9.4. Currently in namespace http://www.w3.org/2005/xpath-functions/map. Available in XSLT, XPath, and XQuery, whether or not 3.0 is available. Requires Saxon-PE or Saxon-EE. Saxon always compares string-valued keys using the Unicode codepoint collation.
