an “empty” notesource is on that looks like this:<literallayout class="monospaced"> <ulink url="http://docbook.sf.net/snapshot/xsl/doc/manpages/"/></literallayout>
</para></footnote> “notesource”:
<itemizedlist>
<listitem>
<para>a number (in square brackets) is displayed inline after the
rendered inline contents (if any) of the notesource</para>
</listitem>
<listitem>
<para>the contents of the notesource are included in a
numbered list of endnotes that is generated at the end of
each man page; the number for each endnote corresponds to
the inline number for the notesource with which it is
associated</para>
</listitem>
</itemizedlist>
The default heading for the list of endnotes is
<literal>NOTES</literal>. To output a different heading, set a value
for the <parameter>man.endnotes.section.heading</parameter>
parameter.</para>
<note>
<para>The endnotes list is also displayed (but without
numbers) if the value of
<parameter>man.endnotes.list.enabled</parameter> is
non-zero.</para>
</note>
<para>If the value of <parameter>man.endnotes.are.numbered</parameter> is
zero, numbering of endnotess is suppressed; only inline
contents (if any) of the notesource are displayed inline.
<important>
<para>If you are thinking about disabling endnote numbering by setting
the value of <parameter>man.endnotes.are.numbered</parameter> to zero,
before you do so, first take some time to carefully
consider the information needs and experiences of your users. The
square-bracketed numbers displayed inline after notesources may seem
obstrusive and aesthetically unpleasing<footnote><para>As far as notesources that are links, ytou might
think it would be better to just display URLs for non-empty
links inline, after their content, rather than displaying
square-bracketed numbers all over the place. But it's not better. In
fact, it's not even practical, because many (most) URLs for links
are too long to be displayed inline. They end up overflowing the
right margin. You can set a non-zero value for
<parameter>man.break.after.slash</parameter> parameter to deal with
that, but it could be argued that what you end up with is at least
as ugly, and definitely more obstrusive, then having short
square-bracketed numbers displayed inline.</para></footnote>,
but in a text-only output format, the
numbered-notesources/endnotes-listing mechanism is the only
practical way to handle this kind of content.</para>
<para>Also, users of “text based” browsers such as
<command>lynx</command> will already be accustomed to seeing inline
numbers for links. And various "man to html" applications, such as
the widely used <command><link xlink:href="http://users.actrix.gen.nz/michael/vhman2html.html">man2html</link></command> (<literal>VH-Man2html</literal>)
application, can automatically turn URLs into "real" HTML hyperlinks
in output. So leaving <parameter>man.endnotes.are.numbered</parameter>
at its default (non-zero) value ensures that no information is
lost in your man-page output. It just gets
“rearranged”.</para>
</important>
</para>
<para>The handling of empty links is not affected by this
parameter. Empty links are handled simply by displaying their URLs
inline. Empty links are never auto-numbered.</para>
<para>If you disable endnotes numbering, you should probably also set
<parameter>man.font.links</parameter> to an empty value (to
disable font formatting for links.</para>
