UDF Platform Difference

When checking the file structure of a disc in isobuster if you right click on the UDF structure then go properties then on the properties box that pops up you click on the advanced tab, where it says platform… now does anyone know what the difference between udf with a platform of windows 95 and udf with a platform of DOS/Windows 3.X is ??

Only Record now max and recordnow deluxe seem to have the 95 platform
