Notes on the Saxon implementation

Since XPath 3.1 (implemented in Saxon 9.7), the serialization parameters may be supplied as a map, or as an output:serialization-parameters element; see the specification for details. See xsl:output for more information on serialization parameters.

The function is available since Saxon 9.3, provided XPath 3.0 is enabled. It replaces the Saxon extension function saxon:serialize. Saxon 9.3 and Saxon 9.4 implemented the 2009 version of the specification, in which the serialization parameters were supplied without a wrapper element: see here. In Saxon 9.5 the implementation was changed to match the 2011 version of the serialization specification.
