ColdFusion MX XSLT limitations?

I found some cleaver code on the IBM DeveloperWorks site which combines several xml source documents and transforms them to HTML.

The problem is, I don’t think ColdFusion MX can handle the xsl document() function. If anyone can get this little app to work in CFMX, I’d love to learn how you did it.
