Here's a case-in-point. In this case there's a mish-mosh of presentational
attributes and a spacer gif in a layout table. While they've added an
empty alt on the spacer gif, the presentational markup cannot be overridden
by user styles or by turning off styles.

<table bgcolor="#999999" width="100%" cellspacing="0" cellpadding="0"
border="0">
<tbody><tr valign="top"><td><img src="/uscmap/images/dot_clear.gif"
width="10" height="5" alt=""></td><td class="lftNavBot">
