XQuery Update 1.0

Saxon implements XQuery Update Facility 1.0, which finally reached Recommendation status on 17 March 2011. All features, including optional features, are implemented.

Update is currently supported only on documents built using the linked tree model.

There are several limitations worth noting:

From Saxon 9.6, if XQuery 3.0 or 3.1 is enabled, then XQuery Update 1.0 syntax may be mixed with XQuery 3.0 or 3.1 syntax.

Saxon does not currently implement XQuery Update 3.0, and there are currently no plans to implement it.
