I agree with Ross, that a new tag should be used. The sign you talk about is not related to maxspeed. Here in Italy, for example, this is achieved through square signs with a blue background, which qualifies them as "information" signs. Instead, max speed is indicated by round signs with a white background and a red border, which means they are "prescription" signs. Also how do you tag maxspeed which is unsigned?

In Italy we've been using something like maxspeed=50; source:maxspeed=IT:urban maxspeed=90; source:maxspeed=IT:rural Ciao, Simone
