It's not a bug, it's the SGML SHORTTAG feature.  In HTML (not XHTML) The 
trailing '/' before the '>' actually closes the tag, and closes the 
whole element in the case of EMPTY elements, such as meta and link. 
Therefore, the '>' is actually a character after the meta element and in 
the head, where there is no character allowed.  See appendix B [1] of 
the HTML 4.01 spec for a brief description of SHORTTAG.

If your going to use the XML syntax, then you should use an XHTML 
DOCTYPE.  If you're going to use an HTML 4 DOCTYPE, then don't use the 
XML syntax for empty elements.
