I was also wondering what is the idea behind Doku_Handler_Nest. It seems
that footnote mode is the only one using it but it is not clear why.
Initially I thought that the nested instructions are rendered separately
to be shown at the bottom of the page. But at least in XHTML renderer
they seem to be rendered sequentially with the rest of the instructions.
Instead of skipping the instructions the renderer temporarily replaces
the output buffer and keeps on going.

Any comments?
