I tried a few variations, and noted that with the default generated
<sup> markup, the problem of a split footnote number occurs only with
the first footnote in a chunk -- subsequent footnotes in the chunk are
rendered correctly (which is, a smaller superscript number and the
hyperlink immediately underneath only the number: <sup>[<a id="d0e490"
href="#ftn.d0e490" class="footnote">1c</a>]</sup>). This is the case for
Firefox, Chrome and SeaMonkey. IE8 breaks the footnote across two lines.
I then found a workaround that renders the first footnote correctly in
most browsers (IE8 still breaks across lines) -- put an empty <a> tag
before the <sup> (though having duplicate <a> tags might have issues
regarding accessibility or validity, and I'm not sure if epubcheck would
pass such a chunk as valid):
<a></a><sup>[<a id="d0e490" href="#ftn.d0e490"
class="footnote">1c</a>]</sup>
But the markup that is rendered most consistently across browsers is to
put the superscript inside the <a>:
<a id="d0e490" href="#ftn.d0e490" class="footnote"><sup>[1a]</sup></a>
This places the hyperlink underline a small distance below the
superscript and makes the square brackets and the number active -- this
could be better than the default markup because there's a slightly
larger active link area.

Hi Dave,
That HTML code looks legit to me. Can you try these variants and see
if any of them work in all the browsers?
<p>Original: earth occur in Australia.<sup>[<a id="d0e490"

XHTML not formatting correctly
Bob,
I've viewed this chunk with Firefox 10, Google Chrome 17 and
SeaMonkey 2.7 - they all show the first footnote the same way as
my screenshots. Internet Explorer 8 actually shows the
left-bracket, then *breaks* the rest of the footnote number onto
the next line! (number and right-bracket). Only IE6 shows the
first footnote number correctly.
Here is the part of the HTML output:
... earth occur in Australia.<sup>[<a id="d0e490"
href="#ftn.d0e490" class="footnote">1</a>]</sup> More ...
This is exactly the same output for the next footnote - it seems
to be a browser problem. Interesting...

Can you show what the generated HTML code looks like?
Does this problem show up in other browsers?

I am producing XHTML 1.1 files with DB5 1.76.1ns and Saxon
6.5.5 - regarding superscript footnote numbers in body text,
the first footnote is not correctly sized to superscript size
- the footnote number and the closing right square bracket
are the same size as the body text (whereas the opening
square bracket is correctly sized). The second footnote
number in the same paragraph is sized properly. See the
attached screenshots.
I have made sure my customisation layer and CSS file is not
interfering. I'm using the markup:
<footnote><para>text...</para></footnote>.
