Hello,
First of all, thanks for this tool, found it very useful.
Below some sample code to include (sRGB) ICC profile and corresponding
OutputIntents to the generated PDF/A. The produced PDF successfully
passes validation.
It would be nice to have the COSName' extension included in the next
release so we won't have to use a homemade build.
Regards,
Elyes

oi.setRegistryName("http://www.color.org";);
COSArray outputIntents = new COSArray();
outputIntents.add(oi);
root.setItem("OutputIntents", outputIntents);
