Maybe there is sth. wrong in my dictionary.
Sorry if so. The word highway itself seems the problem.
But it's not my intention to change things here.
We already have highway=pedestrian. That's satisfactory.
As I said before. I'm trying to combine pgrouting and OSM in a private 
project. I mentioned the need to keep things simple. The handling of 
some tags overloads the data and the complexity for parsing a suitable 
routing table. For my taste even the turning restrictions could be 
handled simpler. But that doesn't matter. Parsing this out is simple.
