Matthew: Proposed the beginning of a comment. Need to verify how the video element works, will ask them tomorrow.

Matthew: Last time we talked about this, we discussed the basics of a proposed comment. I am still working on that and hope to finish that today.

Brian: Write up your comments; I probably shouldn't be writing it since it was submitted by someone from my org.

Luke: Because nothing within the video element is exposed, it's the video element that has focus as far as DOM elements is concerned. The controls within a video element are not specified; they are browser internal.

Matthew: I'll work up the base comment.
