XQuery Update 1.0

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

The XQuery Update specification defines a number of extensions to the XQuery 1.0 grammar. Saxon implements these as extensions to the XQuery 3.1 grammar.

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

There are several limitations worth noting:

Saxon does not currently implement XQuery Update 3.0, and there are currently no plans to implement it. W3C work on this specification has been discontinued.
