I understood it that HTML5 can be used as SGML application (<br>) and as XML application (<br/>). So
the DTD is not enough to distinguish both modes via the DTD. You would have to check the MIME type
(text/html vs application/xml+xhtml).

Sidenote: TYPO3 currently doesn't support valid HTML anyway. All single tags are rendered with a /
(like <br/> and <img/>).
