我需要从无法通过xsd2php创建的xsd文件创建php类

XSD文件： xsd2php显示以下错误- PHP致命错误：未捕获错误：在/var/www/html/xsd2php master/bin/xsd2php:19中找不到类“Symfony\Component\DependencyInjection\ContainerBuilder”

OTA规范中的所有模式文件均根据OTA许可协议中定义的条款提供http://www.opentravel.org/Specifications/Default.aspx
Hotel Reservation Notif请求支持使用预订数据更新其他系统的功能。消息采用推送模式，原始系统将数据推送到另一个系统。始发系统通常是预订来源，如全球分销系统（GDS）、中央预订系统（CRS）或酒店的其他代理。
元素中包含的销售点数据传递的信息允许接收系统识别发送请求或响应消息的交易伙伴。
这表示批次ID。
释放保持之前的时间。

我只是在文件开头添加了这一行

```````

结果将显示在文件中
