Just an update on my previous footnote markup proposal. Håkon Wium
Lie told me in a private email that it wouldn't work alongside
progressive rendering in CSS. From what I understand, it only applies
to paged media however.
The problem is that you can't lay out a page until all the footnotes
for that page have been found; if footnotes are all at the end of the
document -- as in my backward compatible proposal -- then no page
with a footnote can be rendered until the footnote content, at the
end of the document, has been parsed.
So, for progressive rendering on paged media, footnote's content
would need to occur either before the footnote mark in the text, or
at the same place. Looks like we're in a dead end: it's either
progressive rendering or a backward compatible markup.

To draw a parallel, Ian suggested some days ago making <tfoot> legal
when at the end of <table>. This has similar implications: it breaks
progressive rendering on paged media when the table spans on more
than one page (assuming the footer is shown at the bottom of each
page, that is).
So I'm going to ask: where do we stand on progressive rendering for
paged media? and what is the current state of HTML in this regard?
