Yahoo's Terms On Using The Subscription Button Suck

Reading this article by Thomas Korte about promoting your blog using RSS feeds, I decided to add some more subcription button to my page, including a button for MyYahoo.

Until I read the Terms and Conditions. They state that

You may not remove, distort or alter any element of the Button (including the html code) or otherwise change the size or appearance of the Button in any way.

Ah, not allowed to change the HTML code, hum? Too bad the according HTML code generator spits out invalid XHTML code:

<a href="-the yahoo url-">
<img src="-the yahoo button-" width="91" height="17" border="0" align=middle alt="Add to My Yahoo!">
</a>

align=middle? And where is the closing image tag? Sorry, Yahoo folks, none of your buttons on this page.

PS: Generating poor or invalid XHTML isn't specific to Yahoo. Feedster does it ("border=0"), and Newsgator does it, too (not closing the image tag). However, they allow me to fix this.
