Addendum to the new <audio> tag.

While reviewing some documentation on the audio and video tags, I realized
there might be a useful additional tag that could be added that would help
annotate the audio or video.  Instead of a <p> tag containing the text  of
the audio or video, consider a <time> tag. This would help developers
bookmark specific sections of the audio or video, and function as an SAP
channel for video for close captioning.

Thanks
