"Void" is correct:

Documents served with a text/html MIME type must obey the HTML syntax
rules, not XHTML. I couldn't find where the spec says this
normatively, but there's an informative note at the top of the HTML
syntax and XHTML syntax sections.
If you're serving a document with an XML MIME type, <foo></foo> is
equivalent to <foo /> for any value of foo. The validator won't
distinguish and neither will UAs, so use whichever you please.
They're entirely different with an HTML MIME type, and that cannot be
changed at this point due to compatibility.
