Sliders have to have a handle, and that handle has to be somewhere
on the slider. Therefore, it has to have a value within the range. The
default value for anything is usually zero. (In the case of sliders, it
could also be the middle value between the |max| and |min| values.)
You could argue it's illegal (although I have no idea why it would
be), but that's pointless, since a control like a slider has to have a
default value. Now that I think about it, this could be used as an
argument why sliders shouldn't be used for <input type="range">,
although I don't really by that argument myself.
