The file in question is not valid. The <meta> element in the XHTML 1.0
Strict DTD is defined thus:

  <!ELEMENT meta EMPTY>

The SGML System Declaration for XML also specifies:

     FEATURES
         MINIMIZE
             OMITTAG NO
             SHORTTAG
                 STARTTAG
                     EMPTY    NO
                     UNCLOSED NO
                     NETENABL IMMEDNET
                 ENDTAG
                     EMPTY    NO
                     UNCLOSED NO

IOW, the "meta" element is declared as EMPTY -- not allowed to have any
content -- and cannot have an explicit and separate end tag. Thus the only
legal form for the meta element in XHTML is: <meta />.

Does that answer your question?
