前言
carla于0.9.8版本开始支持ioenscenario场景的导入，是通过python脚本的方式进行的，将openscenario文件解析为内置的场景信息，然后在simulator中加载出来。其支持的openscenario版本为1.0版本，但并不是支持openscenario的全部内容，因为有些数据是pythonAPI目前没有办法解析的，因此，对这些carla暂未支持的openscenario做下记录，已备在carla中运行场景时查阅。
不支持的内容
RelativeLane等
在openscenario脚本中使用道路、车道等参考信息时是无法导入至carla的，可通过worldPosition解决。
