How to pass parameter --validate=false to the DITA-OT?

[FrankRalf]

Hello,

I want to set the DITA Open Toolkit parameter "validate" to "false" during PDF generation. How can I accomplish this in the PDF output preset?

I have tried setting DITA-OT Command Line Arguments to --validate=false but get an error because the output preset generates the output via Ant instead of the command line.

Best regards,

Frank
