One of the heritages of previous Siebel releases are the pdfstyle.fst and the pivot.fst files. These files control partly the your PDF output looks and can be found in ...\s_{skin_name}\b_mozilla_4 .
Most of the time the settings are controlled by your .CSS files or the settings you make in your report. Some setting are still controlled by pdfstyle.fst and the pivot.fst (Like Title and Tapedeck).
It looks like Oracle is trying to transfer these controls to the .CSS files, they already did it with the pivot table and the regular. Still it’s handy to know where to “hack” if you have some strange PDF behavior.
