Hi Thomas,

Thanks for the quick reply!

so if I understand correctly:

- Upgrading libisofs to 1.1.0 would produce the correct entries.
- BUT going forward, empty entries are prescribed by RRIP 1.12 and it's
best for the tools (isoinfo) to take that into account.

Am I correct?

Thanks again,

- Daniel
