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.
