New Working Drafts: XQuery Update Facility, XQuery Update Facility Use Cases

Jonathan Robie

The XML Query Working Group just published new Working Drafts of
the following documents.

XQuery Update Facility
http://www.w3.org/TR/2006/WD-xqupdate-20060508/

XQuery Update Facility Use Cases
http://www.w3.org/TR/2006/WD-xqupdateusecases-20060508/

The major changes in the XQuery Update Facility include a change to the
grammar that eliminates superfluous and inconsistent use of curly
braces, and a change to the compatibility matrix to eliminate the
incompatibility between primitive operations "insert into" and "insert
into as last" when these operations are applied to the same target node.

The major changes in the XQuery Update Facility Use Cases include use of
the new grammar and several new use cases, including updates on
recursive structures, updates that create nilled elements, and an update
that moves elements and attributes from one namespace to another.
