The optimum attribute specifies the range where the gauge's value is considered to be an optimal value.
The optimum attribute can be used on the following element: <meter> and must be within the range i.e between min and max. When it is used with the "low"and "high" attribute, it gives an indication where along the range it is considered preferable.
<meter optimum="number"></meter>
number: specifies a floating point number that is the optimal value of the gauge
