Qt 4.7's documentation not respecting the DOCTYPE it shows

When you try to validate a page of the doc (let's say, http://doc.qt.nokia.com/4.7-snapshot/qobject.html), letting the validator choose the right king of document to validate against, it show too many errors, which you can easily correct: end your <div>, use a <span> inside a bloc instead of <div>, use CSS instead of Nokia's properties.

The page: http://doc.qt.nokia.com/4.7-snapshot/qobject.html
The validator errors: http://validator.w3.org/check?uri=http%3A%2F%2Fdoc.qt.nokia.com%2F4.7-snapshot%2Fqobject.html&charset=%28detect+automatically%29&doctype=Inline&group=0
