A workaround i do is exporting from Omnigraffle to SVG, opening it in Illustrator and exporting from Illustrator to EPS. The EPS from Illustrator is with transparency, only without transparency if you decide to add a transparent picture - this transparency will be lost! The EPS from Omnigraffle does not have transparency beside of background - but there are white squares around rectangles... To make it complete, in Omnigraffle arrows as endings of lines - they lead to the absence of the line if you decide to export to SVG from Omnigraffle. That's so much fun! Thank you!! SVG is great!!!
