Is there more to ‘glossary’ definitions than I am seeing?

Since there is a data structure for a glossary term

{code}
<dl>
    <dt>
       TERM
   </dt>
    <dd>
       DEFINITION
   </dd>
</dl>
{/code}

I had hoped there would be functions like “put the glossary out as a sorted list”, or pop-up definition when I roll over the term.
