This is not a consumer issued reject.  It is a CM issued reject, so the private 
data is ignored.  This is no different than several other reject reasons (like 
invalid service ID).  At best we could define the ARI, but if we knew what the 
contents of the ARI should be, then we should use a more specific reject reason 
than 'other'.
