sidebar blogroll error

I’m getting one single validation error after coding one category of my blogroll on my sidebar. I just can’t figure out what I’ve done wrong. Here’s the code:

<?php wp_list_bookmarks('categorize=0&category=2&title_li=<h3>'.__('Blogroll', 'blogtxt').'</h3>') ?>

Can anyone point out what I’ve done wrong?
