WordPress <a href title=”…”

Okay, so I’m displaying my categories using this code: <?php wp_list_categories('title_li='); ?>

The problem is, the links that that outputs have a title tag: <a href="#" title="View all posts filed under Category">Category</a>
I would like to remove the title="..." from that link. How can I manage to do this?

I tried adding: use_desc_for_title=0 but it doesn’t work for some reason.

<?php wp_list_pages('title_li=&use_desc_for_title=0'); ?>
