w3c css validate icon code not xhtml 1.0 strict

Hi,

I don't know if someone has mentioned this to you before or if its normal, 
but your code that one copies on the webpage to show that the page is W3C 
CSS valid, is not XHTML 1.0 strict valid.  The img tag is missing a closing 
"/".  Um and well this second comment is sort of useless but you should 
reduce the border of your XHTML strict valid icon, the code one copies has 
no style defined unlike the css one.

Thank you for your attention,
