Since "If: </x> <DAV:foobar>" would evaluate to "false", unless we adjust the 
definition of NOT, this has to evaluate to "true".

As above, it would just be the opposite of what "If: </x> <DAV:foobar>" would 
evaluate to.  But there remains the question of what "If: </x> <DAV:foobar>" 
would evaluate to.  The guiding priciple here is probably avoiding exposing 
information to unauthorized users.  So an inability to see the object should 
probably be treated the same as the object not existing, so NOT would 
return "true".
