----------------------------------------
Hi Guillaume,
if you like I can handle that for you. Just add the docs to this issue. If you
would like to do it yourself you will need to check out the 'site' directory
from svn which is just below the pdfbox root on the same level as trunk. As
I'm working on migrating to the Apache CMS I can make sure that your additions
are added there too so it's included as soon as it goes live.

> 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.
