PHPDoc用于可变长度的参数数组

我正在考虑使用类似于以下机制的CodeIgniter样式库：

<?php

//
// Library definition
//

class MyLibrary {
  var $foo;
  var $bar;
  var $baz;
  // ... and many more vars...


  /* Following is how CodeIgniter documents their built-in libraries,* which is mostly useless.  AFAIK they should be specifying a name
   * and description for their @param (which they don't) and omitting
   * @return for constructors 
   */

  /** 
   * @access public
   * @param array
   * @return void
   */
  function MyLibrary($config = array()) {
    foreach ($config as $key => $value) {
      $this->$key = $value;
    }
  }
}

//
// Library usage:
//

// Iniitialize our configuration parameters
$config['foo'] = 'test';
$config['bar'] = 4;
$config['baz'] = array('x','y','z');

$x = new MyLibrary($config);

?>

所以我的问题是,有没有一些限制的方式记录配置数组,而不仅仅是纯文本描述？实际指定一个适当的@param [type] [name] [desc],允许PHPDoc解析出有用的值？

除此之外,CodeIgniter真的只是覆盖那些通过$config数组传入的值,它们有效地允许你隐藏私有成员.我不是粉丝,但我被困住了.
