Example - Using Point Rules

    // ...    //---------------------------------------------------//
    $factory = new LayerDefinitionFactory();
 
    // Create a mark symbol

    $height = '24'; // points
    $color = 'FFFF0000';
    $markSymbol = $factory->CreateMarkSymbol($resourceId, 
      $symbolName, $width, $height, $color);
    
    // Create a text symbol

    $fontHeight="12";
    $foregroundColor = 'FF000000';
    $textSymbol = $factory->CreateTextSymbol($text,

    // Create a point rule.
    $legendLabel = 'trees';
    $filter = '';
    $pointRule = $factory->CreatePointRule($legendLabel, 
      $filter, $textSymbol, $markSymbol);
      
    // Create a point type style.
    $pointTypeStyle = $factory->

    // Create the layer definiton.
