Notes on the Saxon implementation

Available as defined in XSLT 3.0 since Saxon 9.4; in XSLT, XPath, and XQuery, whether or not 3.0 is available.

XPath 3.1 version implemented since Saxon 9.7.

Since 9.7.0.6, the behaviour changed (following a W3C Specification change) to allow multiple items to be removed in a single call.

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