ADS 响应必须包含一个有效的追踪事件。至少，跟踪事件可以是Impression跟踪事件。跟踪事件应至少包含一个NonLinear广告。此广告是叠加广告，采用静态、HTML 或 iFrame 资源的形式。
<vmap AdBreak breaktype="linear" breakId="csoverlay"
如果 VAST 响应是带有 breakType of 的 VMAPnonlinear，则可用元数据位于nonLinearAvails根对象内。如果 VAST 响应是带有 VMAP 的 VMA breakType Plinear，或者是没有 VMAP 的普通 VAST 响应，则可用元数据位于avails根对象内。
以下 VAST 响应是一个封装的 VMAP 响应，其breakTypelinear值为。
除了封装的 VMAP 响应外， MediaTailor 还支持breakType值为的封装 VMAP 响应和普通的 VAST 响应。nonlinear
