current_page_item() on archive page? – Possible?

Hey guys,

This might be a tough one…

http://codex.wordpress.org/wp_list_pages

You’ll read under the ‘Markup and styling of page items’ heading;

All list items (li) generated by wp_list_pages() are marked with the class page_item. When wp_list_pages() is called while displaying a Page, the list item for that Page is given the additional class current_page_item.

Is it possible to get this class output on an archive page?

My navigation/site structure is a little unconventional in that it uses category links in its navigation (only time will tell whether I’ve made a blooper here – going for a scalable, robust, architecture): http://twitpic.com/dkqdd

Any thoughts?

Thanks,
L
