<para>If <parameter>table.footnote.number.symbols</parameter> is not the empty string,
table footnotes will use the characters it contains as footnote symbols. For example,
<quote>*&amp;#x2020;&amp;#x2021;&amp;#x25CA;&amp;#x2720;</quote> will identify
footnotes with <quote>*</quote>, <quote>†</quote>, <quote>‡</quote>,
<quote>◊</quote>, and <quote>✠</quote>. If there are more footnotes
than symbols, the stylesheets will fall back to numbered footnotes using
<parameter>table.footnote.number.format</parameter>.</para>

<para>The use of symbols for footnotes depends on the ability of your
processor (or browser) to render the symbols you select. Not all systems are
capable of displaying the full range of Unicode characters. If the quoted characters
in the preceding paragraph are not displayed properly, that's a good indicator
that you may have trouble using those symbols for footnotes.</para>
