[Zope] DELETE Objects

I want to create a python script that deletes a specific file from a folder. For now, the user who is calling the script does not have the Delete objects permission on the folder, only the file which he should be able to delete. I have previously used the delObjects method on the folder to remove the file, but this requires the Delete obejcts permission on the folder itself. I would like to do something like container[entry_id].DELETE() but the DELETE method requires 3 arguments, and I dont know what to give it? Or is it better to go in the delObjects on the container and use a proxy to solve the permission problems? Best regards /Erik
