Hello,

Is there a sane way to stop permission propagation to sublocations?
Let's say I have a site, and somewhere below there is a folder as a
trashcan, unneeded objects get moved to here. Users must not modify
objects in the trash. Users usually will get ModifyContent permission
at the site level.
The easiest way seems to stop propagation of the permission
ModifyContent at the trashcan level. But how? Anybody done something
like this already?
