AFAIK the Master.smil created by Obi (5.1 and 6.0 beta) when using the DAISY 2.02 export is invalid. It actually crashes DAISY Pipeline 1.10 DAISY validator.
job.log
The master.smil doesn't have the #id in the src tag:
<ref title="Title" src="0001.smil" id="ms_0001" />
AFIK correct syntax:
<ref title="Frontispiece" src="gici0001.smil#gici0001" id="smil_0001"/>
At the moment I just delete the master.smil and the DTB validates
Let me know if you need a full example
Thanks
Paul
