[Docutils-develop] Footnote references

I've got the following kludge::

    def visit_footnote_reference(self, node):
        name = node['refid']
        id = node['id']
        number = node['auto']
        for footnote in self.document.autofootnotes:
            if name == footnote['name']:
                break
        self.body.append('<text:footnote text:id="%s">\n' % id)
        self.body.append('<text:footnote-citation text:string-value="%s"/>\n' % number)
        self.body.append('<text:footnote-body>\n')
        self.body.append(self.start_para % '.body')
        for child in footnote.children:
            if isinstance(child, nodes.paragraph):
                self.body.append(child.astext())
        self.body.append(self.end_para)
        self.body.append('</text:footnote-body>\n')
        self.body.append('</text:footnote>')
        raise nodes.SkipNode

What I really ought to do is call for a walkabout on the footnote node,
but I can't quite figure out how to do that.  There's also the issue of
figuring out how to sequence in the <text:footnote-body> tag -- adding
it as part of depart_label() just doesn't appeal to me.

The flip side is that what I've currently got isn't picking up
intra-paragraph formatting.  <sigh>
