(I replaced "name" with "streetname" and something like "relname", which might be shown by an edtior in a relation-list, with "name" to make the second one visible.)

By this, a i.e. bus route may include a single piece of the way (if it leaves the way after a few meters) or the whole way (if it follows it partly). Sorry for my bad english.
