There's a number of use cases, and I don't recall which we were looking at 
specifically at the time (it was many years ago), but off the top of my 
head: being able to jump straight to the main content of the page, being 
able to jump to the page's navigation, being able to style the header and 
footer specifically, being able to move sections up and down the outline 
(e.g. turn a sub-section into a sub-sub-section) without having to update 
the markup (e.g. <h4> to <h5>), being able to mark parts of the page as 
being non-critical (e.g. in the spec, a note or example), etc.

HTH,
