&lt;apre&gt; is defined in the Main RXML parser module.
<p>
Adds or removes prestate options. 

<p>Prestate options are simple true/false flags that are added to the URL
of the page. Use <doc><tt>{if prestate=...}</font></tt></doc> to test for the presence of a
prestate. <tt>&lt;apre&gt;</tt> works just like a <doc><tt>{a href=...}</font></tt></doc>
container tag, but the <tt>href</tt> attribute can be omitted in
which case the current page is used.
