Applies to International.
The Saints property tells Q++Studio which Holidays Sets will be used whenever it encounters a saints token in the current script. This property should not be confused with Saints and Namedays Options, which is used to defined how saints are displayed for each individual DiaryGridLine.
If you have a complex scripts that include many different GridTemplates which may have been coded differently (for example, one grid has the Finnish namedays using the letter "a" while another grid in the same script uses the letter "a" for Swedish namedays) then you can use the Override International Saints/Namedays option of Saints/Namedays Options to override, for each DiaryGridLine, the choice made here for the Holidays Set to be used for Saints. This is analogous to the relationship between the properties Holidays Override and aeiou-Holidays.
