it separates the work into 2 distinct tasks:
if I see a "urban area" sign, I tag maxspeed:type=urban.
I automatically take advantage of the default values existing on 
boundary without having to worry about which hierarchical level is 
responsible for the panel I see, because this info is not visible
on the panel. a BE:VL:urban sign is the same as the one for Brussels.
how to change all BE:urban in Flanders to BE:VL:urban ?
using a is_in with the boundary ?
it shows that the info "the effect of this panel use the rule
for BE:VL" is already in osm. the problem is that we don't use it.

somes minor roads don't have it.
That's what Belgian surrealism is all about. no one is supposed
to ignore the law, no luck if you are bad in geography :)
