"required" | "optional" | "absent"

Specifies whether a stylesheet module requires a global context item; the default is optional.

Saxon availability

Available in XSLT 3.0. From Saxon 9.8, available in all editions. Requires Saxon-PE or Saxon-EE. Implemented since Saxon 9.7. Available for all platforms.

Notes on the Saxon implementation

Implemented since Saxon 9.7.

An earlier draft of the XSLT 3.0 specification defined attributes streamable and use-accumulators (to define which accumulators are available with the document containing the global context item) for xsl:global-context-item. These were briefly implemented in Saxon but have now been dropped.
