Good point. I'll try to implement that, but I see some possible problems 
with the current data flow.

Yes, tried that (the latte) already. Have not found a solution that shows
the right name in address search and name+shield on the map.
I think you found the same result.
I'll try again with roads that only have a ref if I find a way to split 
roads.

In the branch mkgmap has a detection for this "random" case and
it creates no interpolation numbers when the random case is detected.

I thought about this and I think it doesn't work in maps which support
routing. If fear when I add "invisible" and roads and don't add them to the
routing network routing to such an address will not work.
Maybe I'll try that out when the rest is done.
