We need a way to programmatically retrieve the array of values that you can select for the slider, along with the names for those values, so why not data-attributes? One for the names, and one for the values -- I considered just combining it into one data-attribute and doing a hash with the name:value pairs, but I thought this way was better. Still, if people care, I can move to that way (or another way depending on if there is a better way to do it).
