+    <para>For any “notesource” listed in the auto-generated
+      “NOTES” section of output man pages (which is generated when
+      the value of the
+      <parameter>man.endnotes.list.enabled</parameter> parameter
+      is non-zero), if the notesource is a link source with a
+      relative URI, the URI is displayed in output with the value
+      of the
+      <parameter>man.base.url.for.relative.links</parameter>
+      parameter prepended to the value of the link URI.</para>
+
+    <note>
+      <para>A link source is an notesource that references an
+        external resource:
+        <itemizedlist>
+          <listitem>
+            <para>a <tag>ulink</tag> element with a <tag
+                class="attribute">url</tag> attribute</para>
+          </listitem>
+          <listitem>
+            <para>any element with an <tag

+
+    <para>If you use relative URIs in link sources in your DocBook
+      <tag>refentry</tag> source, and you leave
+      <parameter>man.base.url.for.relative.links</parameter>
+      unset, the relative links will appear “as is” in the “Notes”
+      section of any man-page output generated from your source.
+      That’s probably not what you want, because such relative
+      links are only usable in the context of HTML output. So, to
+      make the links meaningful and usable in the context of
+      man-page output, set a value for
+      <parameter>man.base.url.for.relative.links</parameter> that
+      points to the online version of HTML output generated from
+      your DocBook <tag>refentry</tag> source. For
+      example:
+      <programlisting
+        >&lt;xsl:param name="man.base.url.for.relative.links"
+        >http://www.kernel.org/pub/software/scm/git/docs/&lt;/xsl:param></programlisting>
