<vRange>

<vRange> (value range) defines the range of allowed values for a feature, in the form of an fs, vAlt, or primitive value; for the value of an f to be valid, it must be subsumed by the specified range; if the f contains multiple values (as sanctioned by the org attribute), then each value must be subsumed by the vRange.
