How to tag different speed limits in different directions of one street?

How should speed limits be tagged if they are different in the two directions of a street? E.g. reduced speed limit before a crossing road:

    <<       (70)       << |    (50)   <<  (70)  <<     [Speed limit right2left]
    ———————————————————————+———————————————————————     [Street]
    >>  (70)  >>   (50)    | >>       (70)       >>     [Speed limit left2right]
    ~~~ 70 ~~~><~~~~~~~~~ ??? ~~~~~~~~~><~~~ 70 ~~~     [Speed limit tags]

So how to tag this -------^ part of the street?

I'd say maxspeed:forward and maxspeed:backward are the tags you want. "forward" when the car drives in the same direction as the OSM way.

The "*:forward" subtag style is common enough in OSM, and taginfo will show you that it is commonly used for maxspeed too.
