What do current UAs do with known non-option elements and unknown elements in <select>?
Replying to myself, it seems that Firefox trunk ignores all three of text not in any element, text in a known non-option element, and text in an unknown element, when served as text/html, even not including them in the DOM. When served as application/xhtml+xml, they are displayed as would be expected (inside the dropdown, <p> with margins, etc.), but <p selected="selected" does not make the <p> the first thing shown.
So it appears my first idea is infeasable backwards-compatibly. -- dolphinling <http://dolphinling.net/>
