   * An alternative to the formatted number sorting function above (particularly
   * useful when considering localisation which uses dots / periods for 10^3
   * separation rather than decimal places). Another method of overcoming it
   * difficulties of sorting formatted numbers is to have the data to be sorted
   * upon separate from the visual data. This sorting function pair will use the
   * 'title' attribute of en empty span element (or anything else) to sort
   * numerically (for example `<span title="1000000"><span>1'000'000`).
   *
   * Note that the HTML5 `data-sort` attribute can be [used to supply sorting data
   * to DataTables](//datatables.net/manual/orthogonal-data) and is preferable to
   * using this method, which is therefore marked as deprecated.
   * 
   *	@name Hidden title numeric sorting
   *	@summary Sort data numerically based on an attribute on an empty element.
   *	@deprecated
