I would think that there should be a 1:1 mapping between URIs and the
DAV:displayname property, thus making them unique. However, I'm really not
familliar enough with the relevant internationalization issues here. That being
the case, it follows that the DAV:displayname property must not be writable.
That would allow one to give two resources the same display name, violating the
above uniqueness assumption.
