if say in common, road of class A is a major road (numbers from E01 to E99 and even numbers from E101 to E129), road of class B is shorter road and with lower significance. If we get network of e-roads of class A, we should get united network, if we get network of e-roads of class A and B, we should get more complicated united network. I think, that link between road of class A and road of class B is better tag as AB_link. It gives us possibility to get united network of roads of class A (we get e-roads of class A and relations with A_link).
