I have a few taxonomies and it would be nice to be able to sort by two at time with a permalink. For example, I have two taxonomies, design-show-year and designer-or-firm. I'd like to have this permalink to get a listing of all these that match:
/design-show-year/2011/designer-or-firm/pete-klein/
Is this possible using the WordPress system by doing a rewrite and piping that into index.php, or can WordPress only handle one taxonomy at a time?
