That should really be "mode" or "timing", since it's describing a
display mode/timing not a display. I believe the latest messages in that
thread indicate a similar change will be made to the proposed Linux binding.

It should really be a sub-node; like:
panel {
... all the panel-specific stuff from this binding ...
modes {
default {
... all the stuff from displaymode.txt ...
};
};
};
Since the panel itself and the (potentially, list of) modes it can
support are separate things.
