I agree. W3C recently published a proposal on how to achieve
footnote/endnote presentations using the same markup [1]. The proposal
is quite simple. Given this markup:
<div class=note>..</div>
you would achieve footnoes with:
.note { position: footnote }
ane endnotes with:
.note { position: endnote }
Comments welcome.

Bert and I used sidenotes extensively in our CSS book [3]. The book
was written in HTML and we used negative margins to achieve the
effects we wanted. Here's some sample code [4], as well as an article
describing the efforts [5].
