Dears,

I'm probably not the first one who would like a "deep link" icon
after HTML headings (and maybe figure and table titles, too).

In some wikis (here: Trac) it's implemented like this:

     <h2 class="section" id="Something">
         Something
         <a class="anchor" href="#Something"
             title="Link to this section"> ¶</a>
     </h2>

The paragraph symbol is typically hidden and only visible when
hovering:

     * > .anchor:link, * > .anchor:visited {
         visibility: hidden;
     }

     h1:hover .anchor, h2:hover .anchor, h3:hover .anchor,
     h4:hover .anchor, h5:hover .anchor, h6:hover .anchor,
     span:hover .anchor {
         visibility: visible;
     }

Has someone already created an XSL template to get the same
effect with DocBook and can share it here?

Thank you!

Martin
