All line-oriented realations (route, multipolygons, ...) should be sorted, 
so that they build straight lines. JOSM supports this with automatic 
sorting and also display of continuity. Currently there exists no relation 
type which explicitely requires a sorted relation (at least none I'm aware 
of). So for now the order is mainly relevant for human users to do easy 
error checking. Sorting order of route relations may be relevant in other 
contexts in future as well.

Simply Press the download button to download the incomplete members.
