Ick, did I really say that? What I meant was that XHTML requires all
elements to be closed, even if they are empty.

Either is valid according to the XML and XHTML specs. It's not
*recommended* to use a closing tag, but it's still valid.
"The representation of an empty element is either a start-tag
immediately followed by an end-tag, or an empty-element tag."
http://www.w3.org/TR/2004/REC-xml11-20040204/#sec-starttags
"Empty elements must either have an end tag or the start tag must end
with />"
http://www.w3.org/TR/xhtml1/#h-4.6
Incidentally, the XML spec (see link above) defines elements without any
content "empty", regardless of whether they are defined as EMPTY in the
DTD.
