Sure.    This fails to validate because a:Root isn't legal.  It also fails 
to validate because a:child/@covertchannel isn't defined in the DTD. 
Imagine instead that the attribute is xml:id.  So that's a false positive 
-- validation failed, but the document is okay.

<a:Root xmlns:a="http://www.used.org";>
        <a:child covertchannel='foo'>true</a:child>
</a:Root>

        /r$
