In ARIA 1.1, the implicit/default values for aria-valuemin, aria-valuenow, and aria-valuemax are as follows: For roles other than spinbutton: * Default for aria-valuemin is 0. * Default for aria-valuemax is 100. * Default for aria-valuenow is half way between aria-valuemax and aria-valuemin. For spinbutton: * Default for aria-valuemin is that there is no minimum value. * Default for aria-valuemax is that there is no maximum value. * Default for aria-valuenow is 0. We currently are returning 0 for all non-specified values. We need to decide how to expose "no minimum/maximum value." At least in the case of ATK/AT-SPI2, we need to return something, and the something is expected to be a number. My proposal is that we expose the values we use to constrain input type="number": -std::numeric_limits<float>::max() to std::numeric_limits<float>::max().
