devio on "XML Export uses atom: namespace without declaration"

I wrote a tool that transforms the WordPress Export XML file using XSLT to generate HTML and Word HTML files based on the XML export.
http://devio.wordpress.com/2010/01/18/wpxslgui-wordpress-xml-export-converter/

However the XSLT transform fails because of the element atom:link which uses the atom namespace which is not declared in the rss root element,
thus requiring manually editing the two occurrences.

Solution: add xmlns:atom declaration to the rss element.
