In HTML4, the children of a form element must always be block-level.

However, that means that a cell or <li> would not be able to contain a
form that itself contained an <input>, even though the <li> could contain
one directly.

The assertion above is attempting to correct this, by allowing the
semantic of the ancestor to be propagated down.

However, <div> elements are semantic-free. So they have no semantics to
propagate. That is why they are excluded.

The stylesheet has no effect on the allowed content models.

Thanks to your comment I did just notice that I'd omitted to mention LI
and DD elements though, so I'll fix that.
