Exactly. This is what I understood to be the purpose of DIV (and the
CLASS attribute in general): use the CLASS attribute to trigger al
kinds of formatting. After all, folding is not structural, it's a
layout style.
In my style sheet proposal there is a property called "minimized",
that can be applied to any element (see
<URL:http://www.w3.org/hypertext/WWW/Style/>).
