While not mandated by the XML structure, the XML document we return is usually sorted - nodes, ways, relations, each in ascending ID order. Because a way or relation may require additional nodes to be included that lie outside of the bounding box, we can only return the nodes after we have processed ways and relations. For the computer literate, all this information is available here: http://trac.openstreetmap.org/browser/sites/rails_port/app/controllers/api_controller.rb#L87 This could of course be alleviated by allowing the XML to be mixed, i.e. some nodes, then some ways, then some more nodes and so on. Then, one would only have to find a good way to have Ruby stream the results, something which is, as far as I understand from previous posts on this list, not a core feature of Ruby.
