JOSM can also handle incomplete data sets, where referenced objects are 
missing. For relations this is obvious. For other types not so much.

Anyway that's a feature. :-) But usually it is not recommended to 
use that feature unless you really know what you are doing. That's why 
most suggested XAPI/Overpass/API requests include the referenced objects 
to reduce trouble, but it works without.
