Importer for network edges stored in XML.
This SAX-handler parses edge information and stores it in the given container.
revalidate node retrieval
One day, one should rethink the order of parsing. Now, the handler is able to load edges, using information from the types, first, and extending them by given information. In addition, if the read edge is already known, it's values are also used. Then, defining vehicles allowed per lane, and additional edge split definitions add some further complexity. This all works somehow for most of our use cases, but it's definitely not as consistent that everything what seems to be possible would also work appropriately.
