Generic TextGrid URI should reference the latest revision that is accessable (readable) with current permissions
As observed with the list of approved services: # create and publish an object, let's call it textgrid:hk21.0 # create a new revision of it -> textgrid:hk21.1 When someone who has no permissions in textgrid:hk21's project tries to access the object via the generic URI textgrid:hk21 he gets a permission denied fault for textgrid:hk21.1, although he would be able to read the previous revision, textgrid:hk21.0. This currently occurs, e.g., while someone is revision the list of approved workflows.
