 Currently Fusion only uses the CLASS->NAME when setting the legend label
 for classes. It is desirable to have the same level of control that is
 available via METADATA layer naming in the legend. The most appropriate,
 and seemingly standard way to do this is to check for a CLASS->TITLE and
 use that in the legend and default back to the CLASS->NAME if not defined.
 The following small change to the MapServer LoadMap.php, starting around
 line 360, would be needed:

 {{{
 //create classes and slot them into the scale breaks
 for ($j=0; $j<$layer->numclasses; $j++) {
     $oClass = $layer->getClass($j);
     $classObj = NULL;
     // Use formatted legend label as defined by CLASS->TITLE, fallback on
 CLASS->NAME
     $classObj->legendLabel = $oClass->title != '' ? $oClass->title :
 $oClass->name;
     $classObj->filter = $oClass->getExpression();
     $classMin = $oClass->minscale == -1 ? $layerMin :
 max($oClass->minscale, $layerMin);
     $classMax = $oClass->maxscale == -1 ? $layerMax :
 min($oClass->maxscale, $layerMax);
     $classObj->minScale = $classMin;
     $classObj->maxScale = $classMax;
     $classObj->index = $j;
     for ($k=0; $k<count($aScaleRanges); $k++) {
         if ($classMin < $aScaleRanges[$k]->maxScale && $classMax >
 $aScaleRanges[$k]->minScale) {
             array_push($aScaleRanges[$k]->styles, $classObj);
         }
     }
 }
 }}}
