I've been asked to look into this issue, so I committed a partial and temporary
fix based on the latest patch:
Footnotes in table headers and footers are not handled yet, and anyway I think
it's best to wait for clarification from xsl-editors before implementing
anything (which gives us a couple of months ;-) ).
That doesn't prevent you from exploring your ideas above, though. I await your
