Brazil has no official system of classification (there is an
"administrative" classification, which the Brazilian community found
useless to determine the way's "importance"), so we've come up with
this general recommendation (which may not be followed closely, in
which case the mapper should add a note explaining why):

Visibility is an interesting criteria, do you take it into account
when deciding classification? Do you tag it?
