Maybe boundaries are in the database for the renderers only ;-)<br>

Seriously... I can reply.<br>

<blockquote type="cite">Don't forget the fundamentals : OSM is a
geospatial database containing geospatial data. If you are a

I'm using boundaries for computing localisation of things.<br>
I never have studied compuning. But i'm able to manage a postGIS
database, to write queries with spatial functions with jointures,
and to get some good results. It is not so hard.<br>
And somebody making requests with where clauses such as WHERE
"addr:country" IS IN (...) is probably able to make a jointure.<br>
<br>
IMHO addr:stuff may be necessary in the way that addr:stuff is not
exactly geolocalisation and can differ from ST_WITHIN results. But
it is optionnal for only such cases.<br>
