Icon markup for valid XHTML+RDFa

Hello,

there is a small bug in the icon markup for valid XHTML+RDFa: prefix 'dct'
is not associated with a namespace. 
Bugzilla shows a correct example:
http://www.w3.org/Bugs/Public/show_bug.cgi?id=6525

<p about=""
     resource="http://www.w3.org/TR/rdfa-syntax"
     rel="dct:conformsTo" xmlns:dc="http://purl.org/dc/terms/">
    <a href="http://validator.w3.org/check?uri=referer"><img
        src="http://www.w3.org/Icons/valid-xhtml-rdfa"
        alt="Valid XHTML + RDFa"   /></a>
</p>
