Hi,
        Following up from my previous post and having read some more of the
posts concerning classification here is a slightly modified version of the
XML example layout:

        </classification>
        
        <content
                title="" />
                
                <!-- 
                        Article body goes here, using, possibly,
                        pretty standard HTML tags: <h1>, <h2> etc, 
                        <p>, <em>, <strong> and so on.
                -->
        </content>      
</article>

        Note the new <classification> section containing any number of
subjects allowing an article to be classified under an arbitrarily number of
subjects/categories
