java.lang.Objectnet.sf.saxon.sort.NumericComparer
A Comparer used for comparing sort keys when data-type="number". The items to be compared are converted to numbers, and the numbers are then compared directly.
This class is used in XSLT only, so there is no need to handle XQuery's "empty least" vs "empty greatest" options.
