Hi

I am the one who prepared the import of the PlusBus zones. When I
decided to use the name tag I was not aware that the mapnik style
renders them unconditionally otherwise I would not have imported the
data without warning.

In my opinion the name tag is used as a general purpose tag in OSM for
names of all sorts of things. So, it appeared quite natural to use it
for recording the names of the plus bus zones as well. From the other
tags renderers can easily guess what type of object the name belongs to
and the decide if it should be displayed. So there is no need to use
namespaced versions of the name tag just to prevent the renderer from
displaying it.

Cheers,
Christoph
