http://141.13.60.18:8080/geoserver/www/wfs-test5.htm . It´s the product of a
project at my university where we mapped all letter-boxes, stamp-automates,
parcel-stations and phoneboxes in our town (Bamberg).

P.S.: If you see something in the code that could cause problems feel free
to let me know :)
