<iframe src="//www.youtube.com/embed/my-video" width="225" height="150"></iframe>

当我通过Chrome辅助功能审核运行网站时,我在iframe中收到以下错误：

[Severe] ARIA attributes which refer to other elements by ID should refer to elements which exist in the DOM (3)
See AX_ARIA_02 for more information.

知道如何解决这个问题吗？

====更新

我注意到了其他错误：

[Severe] Controls and media elements should have labels
See AX_TEXT_01 for more information.
<video class=​"video-stream html5-main-video" style=​"width:​ 225px;​ height:​ 150px;​ left:​ 0px;​ top:​ -150px;​ transform:​ none;​">​</video>​

和

[Severe] Elements with ARIA roles must ensure required owned elements are present (3)
See AX_ARIA_08 for more information.
<div class=​"ytp-playlist-menu-items" role=​"menu">​</div>​
<div class=​"ytp-related-menu-items" role=​"menu">​</div>​
<div class=​"ytp-menu" role=​"menu" id=​"ytp-main-menu-id">​</div>​

据推测,Youtube视频播放器不符合ARIA标准吗？
