Someone (sorry, now I lost his name) recently posted about wanting
to use \label and \ref to refer to footnote numbers. Someone else
posted that the problem of the original poster had to do with lack
of \protect.
I was having the same problem and defined my own counter, which
works, but is tedious. After this discussion I tried putting
\protect{\label{fn:xx}}
inside a \fn
and
\ref{fn:xx}
in the text.
Lo and behold, it worked.
But then I went to latex.tex and looked at its cross-referencing
section. It explicitly says that \label and \ref works only for
referencable counters, and the footnote counter is not referencable.
So my question is
(are)
1. Why does the reference to a footnote work?
2. Will some unexpected problem show up (the night before the book
is due at the publisher)?
3. Are there lots of other undocumented features in latex?
I am using latex 2.09
