易趣交易API退货政策类型

我正在尝试创建一个脚本，将项目添加到我的测试ebay帐户中。但我遇到了一个问题，我不确定我是否有错误的文件集？但它似乎与文档不匹配（或者我读错了）。

我拥有的文件集是支持527的PHP工具包。还有支持515的PHP工具包。两者均来自https://www.x.com/developers/ebay/php-accelerator-toolkit-ebay-trading-api-edition

我通过另一个关于堆栈溢出的问题找到了这个很棒的脚本https://github.com/iloveitaly/ebay-php/blob/master/eBayCommon.php

我一直在这里查看在线帮助文件：http://developer.ebay.com/devzone/xml/docs/WebHelp/wwhelp/wwhimpl/js/html/wwhelp.htm

这是我得到的错误：PHP致命错误：找不到类"ReturnPolicyType"

我的理解是，每个"类型"都应该有一个文件——有一个用于CategoryType和AmountType，但没有用于ReturnPolicyType的文件。而且我所拥有的任何文件都没有提及它。。我是不是看错了？
