high

The lower numeric bound of the high end of the measured range. This must be less than the maximum value (<code>max</code> attribute), and it also must be greater than the low value and minimum value (<code>low</code> attribute and <strong>min</strong> attribute, respectively), if any are specified. If unspecified, or if greater than the maximum value, the <code>high</code> value is equal to the maximum value.
