Zend_Reflection没有'；t获取某些类的docblock

我正在尝试使用Zend_Reflection来读取某些类的文档块：

这是我的代码

  $r = new Zend_Reflection_Class($class);
  $docblock = $r->getDocblock();

它适用于具有如下文档块的类：

/** @see Zend_Barcode_Renderer_RendererAbstract*/
require_once 'Zend/Barcode/Renderer/RendererAbstract.php';

 */
class Zend_Barcode_Renderer_Image extends Zend_Barcode_Renderer_RendererAbstract

但对于以下类别，即条令2实体定义，它不起作用，

<?php
namespace DbEntities'Entity;
/**
 * Class for archived companies
 * 
 * @category DbEntities
 * @package Ycode_DbEntities
 * @copyright Copyright (c) 2012
 * @licence Porprietory Code 
 * @Table(name="Archiveddeal",
 *      indexes={
 *          @index(name="textualIdentifier_idx", columns={"textualIdentifier"}),
 *          @index(name="rank_idx", columns={"rank"}),
 *          @index(name="realunique_idx", columns={"realunique"}),
 *          @index(name="coordinations_idx", columns={"latitude","longitude"})
 *      })
 * @Entity
 * @HumanFriendlyName = "Archived Companies"
 * @author Jim
 */
class Archivedcompany extends 'Application_Model_Archivedcompany{

它在我的代码的第2行抛出了以下错误：

 No valid tag name found within provided docblock line

第一个文件的$class的值是"Zend_Barcode_Render_Image"，对于第二个文件，我尝试了"DbEntities''Entity''Archivedcompany"answers"''DbEntities''Inventity''Archivedcompany"，它们都返回了相同的错误。

我不确定是否是命名空间混淆了ZendReflection，当我使用PHP的Reflection时，一切似乎都能正常工作

 $rc = new ReflectionClass($class);
 $comments = $rc->getDocComment();

如有任何帮助，我们将不胜感激。
