IIRC we wanted to just add a new char the propfind permissions element. I implemented it with I (as in Initiate Download). The permissions are all positive, but this would make new clients incompatible with old owncloud or ocis versions.

So I decided to add an X to indicate that a resource can be securely viewed in cs3org/reva#4694
