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

[Jonathan Robie <jonathan.robie@datadirect.com>]

      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/)
<http://www.w3.org/TR/2006/WD-xqupdate-20060508/#id-log-050707>

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