Hi WanMil, I still don't understand. Please give an example where mkgmap:road-speed-class has to be used because mkgmap:road-speed will not work. Gerd

Hi WanMil,
I fear I don't understand the meaning of this new tag. Docu says: "A value between 0 and 7. Overrides the road_speed definition in the element type definition if this tag is set."
We have mkgmap:road-speed which allows to increment, decrement or override the road speed value in the element type definition. Why did you introduce this new tag?
mkgmap:road-speed already was already used so I could not just change its meaning. mkgmap:road-speed-class defines the speed classification whereas mkgmap:road-speed can define or modify a speed classification. But how do you want to modify an already set classification? That's not possible in the style because you don't have arithmetic expressions. That results in having mkgmap:road-speed-class which defines speed class (or better overrides the class defined in the GType) and a modifier mkgmap:road-speed. I propose to use mkgmap:road-speed as modifier only (prefixed with +-) but I could not remove the usage without prefixed +- because that would break existing style sheets.
