GET /api/0.6/map?bbox=left,bottom,right,top &select=[node|way|rel]

Hope this is the right place to ask.

From: http://wiki.openstreetmap.org/wiki/API_v0.6

Could an extra parameter be added to the call? At the moment I’m only interested in nodes but get a lot of overhead in ways and relations.

A parameter like: &select=[node|way|relation]

This would reduce traffic.

This can be done with Xapi.
