Dear J.Pietschmann and fellow foppers, First, thank you for offering at least a solution! I was used to equal width columns in tbl and troff documents, but wasn't aware of the feature in FOP.
However, you state "if there is no explicit width, there is no point in centering it". If I knew the width in advance, then I could specify the correct start-indent value. I simply want a collection of blocks to be centered on the page and I'm happy for each block to use as much horizontal space as it likes.
