RE: HOW_TO_IDENTIFY_LOCK_OWNER

   From: Julian Reschke [mailto:julian.reschke@gmx.de]

   Well, if the set of principals with the ability to unlock the
   resource is bigger than one, why not report all of them (or a
   subset whicht the server thinks makes sense)?

That's exactly what the DAV:acl property would do (i.e.
the ACEs for DAV:can-unlock).
