XQuery Update Facility 1.0 published as Last Call WD

Andrew Eisenberg-2

The W3C XML Query WG published the following documents as Last Call WDs early last week:

        XQuery Update Facility 1.0
       http://www.w3.org/TR/xquery-update-10/

        XQuery Update Facility 1.0 Requirements
       http://www.w3.org/TR/xquery-update-10-requirements/

        XQuery Update Facility 1.0 Use Cases
       http://www.w3.org/TR/xquery-update-10-use-cases/


The XQuery Update Facility abstract says:

        "This document defines an update facility that extends the XML Query language,
        XQuery. The XQuery Update Facility provides expressions that can be used to
        make persistent changes to instances of the XQuery 1.0 and XPath 2.0 Data
        Model."

The XQuery Update Facility adds 4 new updating expressions to XQuery 1.0; insert, replace, rename, and delete. These expressions modify instances of the XQuery 1.0 and XPath 2.0 Data Model (XDM). The XQuery Update Facility also adds a non-updating expression, transform, which returns an XDM instance that has been created by copying existing XDM instances and then modifying them.

The review period for these Last Call WDs ends on Oct. 31, 2007. The status section of each document specifies how you can provide comments to us.
