[OSM-talk] OSMXAPI question: is it me, or...

Taking a closer look at the data, there are some strange things indeed. 
However, these are not new, they are already in there several weeks.
I retrieve all routes in the netherlands: 
relation[network=rcn][bbox=2.7984557419334006,50.62642256377723,7.388298070963748,53.954129036190224]

Problems:
- some relations are outside the bbox, for example relation 5881 (at 
least, as far as I can see, I didn't compute the bbox of the relation)
- quite some nodes are missing (they are referenced by ways that are 
returned)
- a few ways do not contain any nodes, for example way 24828122, whereas 
the main api returns two nodes

For now I just ignore these, so it's no problem to me. But if you want 
more information on these problems, I can easily give a list of all 
nodes/ways with the last two problems.
