highlight current sub-category

I’m looking for a way to highlight the current sub-category. Highlighting the current parent category is easy enough, thus if you use <?php wpsc_print_category_classes_section();?> it will print wpsc-current-cat if you’re current category is a parent category, I’m looking for something similar though for sub-categories, it doesn’t seem to be documented either, so I’m not sure if it’s possible.

Anyway at all to detect the current category if you’re on a sub-category page? Any suggestions would be greatly appreciated!
