Hi Jörg, 

as I understand, even with external versioning its not possible to update a 
doc *without changing/not incrementing* the version number at all. 

1. User A loads DOC123 with version 20 and locally starts editing critical 
fields
2. User B simply loads DOC123 to view/read only. A view counter will be 
incremented, so also the version number will be set to 21 (or something 
higher with external versioning, but not to 20 again)
3. User A tries to send the updates from (1) with version number 20 to 
ensure he has the current version and update will fail, cause version 
number has changed

Thanks
Joa
