Hi Baoqiu and Mario,
clearly, writing =double[3][3]= is the correct solution to this problem.
As for the behavior of [3][3], this is not clearly defined. Neither
the LaTeX
nor the HTML exporter handle this case gracefully, as in producing
meaningful output.
Maybe the right thing would be to have them both treated as a footnote
reference, but that would also require changes to org-footnote.el.
These changes are not entirely
trivial, as far as I can see now.
So uness you are willing to dig into org-footnote.el to changes this,
the
easy solution would be to simply catch the problem we have now in the
docbook exporter, so that it does not crash.
