Also add maxspeed:zone=school for a zone 30 which has the status of a "school 
zone" in Belgium (has the same zone 30 signs but with an extra traffic sign on 
top and has a special definition in our traffic code). There's also a 
"vacation zone", but I don't think anyone has been tagging those in a special 
way.

btw, I created the maxspeed:zone= tag because it (a) allows extension to a few 
other zonal restrictions (no parking zone etc), and (b) allows extra values 
like "school".
