Validator warning in case of multiple traffic signs

[anonymous]

The following tags on a node create a validator warning:

traffic_sign=maxspeed;overtaking
maxspeed=70
overtaking=no

When the tag traffic_sign is changed to traffic_sign=maxspeed, the validator warning disappears.

In this case the warning is incorrect. In fact there are two signs at one place - one above the other.

The validator should not check for traffic_sign=maxspeed but instead for a value equal to the following regular expression: ^{(.*;)*maxspeed(;.*)*$ (keep in mind: I'm not a regexp expert)}
