Edward, Matt, Jonas,
I've created a CP for issue 204 which I think includes the arguments from both your CP and Laura Carlson's. We've been discussing this in the accessibility TF for the last couple of days, and I'd very much like your feedback. My hope is that we can come to a single CP that address everyone's concerns, and that you can withdraw yours.
Here is my CP:

Here are the threads discussing it over the last couple of days.
