We could do both. The <outline> element would create a shadow dom, but a
createOutline() method would just create the list of sections and leave
formatting to the developer. All of those limitations could also apply to
<outline> within a section.

Just brainstorming here - this needs properly thinking through. But it also
means that the outline algorithm suddenly becomes useful and is not just a
suggestion for how to create an outline from the DOM.
