Hello,

I would appreciate any helping hint on this problem:

- OO.org 2.0 document archives (*.od?) with a digital signature (documentsignature.xml (or whatever it's named) inside the archive) cannot be opened with 7-zip 4.23
- neither OO.org 2.0 document archives (*.od?) _without_ nor such archives _with_ a digital signature can be opened with 7-zip 4.29

Thanks
