Hi,

You may perhaps have a look at the Monobook/grease Skins where I
implemented such kind of workarounds in order to handle markup
definition rendering within specific template areas.

Excerpt from grease/grease.tmpl:
  ...
  <h1 class='titlepage'><!--function:RenderPart title--></h1>
  ...

Excerpt from grease/grease.php:
  ...
  function RenderPart($pagename, $part, $strip = '') {
    global $SkinPartFmt, $PCache;
    $n = "skin_$part";
    if(!isset($PCache[$pagename][$n])) {
      $t = MarkupToHTML($pagename, "<:block>{$SkinPartFmt[$part]}",
array('escape' => 0));
      $PCache[$pagename][$n] = $strip ? preg_replace($strip, '', $t) : $t;
    }
    print $PCache[$pagename][$n];
  }
  ...

Roughly, the function takes a markup source fragment from the
$SkinPartFmt definition array, renders it as an unenclosed block of
text (no <p> markers), then does some optional housekeeping on the
resulting html and stores it in the page cache for future reuse to
prevent extraneous generations before outputing the result.
