ulex:NumericRangeIndicator

True if the service provider supports queries on ranges for numeric elements, such as a range on a boat length.  This also includes "open-ended" ranges, such as a search on a boat length less than a specified value.  Note that a service provider may support range searches on some numbers and not others; this Boolean does not indicate what elements, just that the service provider supports some level of numeric range searches; false otherwise.
