Without knowing how you plan on solving the use case for your
proposal, it's hard for me to answer how I would solve it in my
proposal.

Whatever syntax you use to style one of the buttons in your proposal,
would likely allow you to style both buttons in my proposal. I think
there are pseduo elements defined in some CSS spec which might be
useful here. If we can give the pseudo-elements arguments, we could
probably even allow you to use different styling on the two buttons if
people really want to do that. But that doesn't seem terribly
important to me.

My point is that it seems to me like you can get 80% there without
requiring any special markup on the page. And you can get 100% there
by just looking at the mime-types main parameter. I.e. display an
extra camera button for @accept="image/...", an extra microphone
button for @accept="audio/..." and an extra video button for
@accept="video/...".

That could be an ok solution I agree.
