--------------------------------------------
Yes I need some help for documentation.
Is there some doc on how to make doc somewhere ?
> Extending COSName to produce PDF/A with correct OutputIntents

> 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.
