In the slides 2.0 distribution, only the root element slides and the element section contains a speakernotes element.
Usually I would prefere notes to be associated with a specific foil.
I would therefore propose to change the foil element to:
<!ELEMENT foil (foilinfo?, title, subtitle?, titleabbrev?, speakernotes?,
(%divcomponent.mix;)+)>
