    The Interval selector defines an interval value. An interval must be defined using a point type that supports comparison, as well as Successor and Predecessor operations, and Minimum and Maximum Value operations. The low and high bounds of the interval may each be defined as open or closed. Following standard terminology usage in interval mathematics, an open interval is defined to exclude the specified point, whereas a closed interval includes the point. The default is closed, indicating an inclusive interval. The low and high elements are both optional. If the low element is not specified, the low bound of the resulting interval is null. If the high element is not specified, the high bound of the resulting interval is null. The static type of the low bound determines the type of the interval, and the high bound must be of the same type. If the low bound of the interval is null and open, the low bound of the interval is interpreted as unknown, and computations involving the low boundary will result in null. If the low bound of the interval is null and closed, the interval is interpreted to start at the minimum value of the point type, and computations involving the low boundary will be performed with that value. If the high bound of the interval is null and open, the high bound of the interval is unknown, and computations involving the high boundary will result in null. If the high bound of the interval is null and closed, the interval is interpreted to end at the maximum value of the point type, and computations involving the high boundary will be performed with that interpretation.
