@Mr.Wizard I don't really know how it works. I don't think I can use it since "you never know what to expect" is not an option. I don't mind that this feature is not available since I agree there are not so many folks waiting for it. (or maybe noone is waiting for it and advanced stylesheets setups are used rarely because stylesheet system is cumbersome and limited?)
@Mr.Wizard Anyway, FormatType doesn't seem to be related. I don't have any reference to Core/Core-based stylesheet so why? Moreover If my second reference consists only of StyleData["Notebook", Background->...] it is NOT taken into account either.
@Mr.Wizard So I just have to abuse specific needs of my setup, create multiple stylesheets for each available combination of parameters and go on. I hate this...
