div inside link may throw a validation error.

customer/simple_products_list.tpl is called from other areas like modules/Recommends/recommends.tpl (Upselling Links). It has its own $product called from within its own foreach loop. This is a separate $product from the one on the product details page. Most likely descr is not in the simple list and would have to be added through a customization.
