On a taxonomy term page, the taxonomy term info is shown first, followed by related nodes. I want to add a wrapper div around the related nodes (ex. class="related-nodes").
taxonomy-terms.tpl.php controls the display of the taxonomy term's fields, but I'm not sure how the nodes show up. I was thinking about making a node template for the taxonomy and doing something like render($content['nodes']). However, I'm not sure what the $content key would be for the related nodes.
