When aligning characters on baselines, 'mathematical' identifies the baseline used by mathematical symbols [1]. You've aligned the center of the white rule on the 'mathematical' baseline of the parent area [2][3]. You could have used the 'baseline-shift' property to shift the rule up or down rather than chancing upon a baseline that matched what you want. You could perhaps have used a checkbox-like character from, e.g., Zapf Dingbats or WingDings (assuming the fonts are available to you) instead of making a checkbox with fo:leader. > Sadly enough there where no really bad FO in the original solution > like nested tables. Do you have other, more necessary SVG graphics? My expectation is that you saved more of the 20% by replacing the SVGs than you did by replacing the table.
