XHTML 1.0 Strict

Dear Sir or Madam, 

your code for CSS Valid webs:

<p>
 <a href="http://jigsaw.w3.org/css-validator/">
  <img style="border:0;width:88px;height:31px"
       src="http://jigsaw.w3.org/css-validator/images/vcss" 
       alt="Valid CSS!">
 </a>
</p>

is not XHTML 1.0 Strict valid. If I place it to my XHTML 1.0 Strict valid page, it is valid no longer. There is the end tag missing.
I believe it should be

<p>
<a href="http://jigsaw.w3.org/css-validator/">
  <img style="border:0;width:88px;height:31px"
       src="http://jigsaw.w3.org/css-validator/images/vcss" 
       alt="Valid CSS!"/>
</a>
</p>

Yours sincerely

Sarka Canska
