Hi Jan,
The DITA Open Toolkit uses ANT to build docs. This is a question that comes up
occasionally on the DITA Users forum.
A number of document CMS products use the DITA Open Toolkit, so a large number
of Technical Authors can potentially see this message.
If it could be suppressed, I'm sure a lot of folks would be highly delighted.
Many thanks,
David
