Have you tried to hide the attachments linked to PR or Document (application data) . Basically the WTDocument info page should be visible to the users but the attachments should be hidden . Foget the ACL's , I tried to check if Security Labels would be helpful , but unfortunately they are supported for Document / PR and not for the attachments linked to these objects. Moreover Application Data column in DB has no column for Security Label ! ...
Any help would be highly appeciated and highly useful. Thanks
