No, that one works. "addr:street" is used for determining the street
the house number belongs to. Further address details are taken from 
that street. That even includes the name of the street itself, which
comes in handy in multi-lingual areas where you can put all the name:xx
tags on the street and just have one addr:street on the address with
the contents of the name tag of the street.
