Style Sheets in QuarkXPress
A Style Sheet in QuarkXPress is a collection of text or paragraph formatting attributes with a name.
Style sheets can be quite useful and are generally handled transparently in diary generation.
The only potential issue is that during diary generation, we are mixing different QuarkXPress documents that might use different style sheets with the same name but different definitions. To prevent against such issues, the warnings 181445 and 181450 warn you if you are mixing QuarkXPress documents containing the same-name style sheets defined differently.
