Hi Paul,

Thanks for answering.

This has luckily not been done for the municipalities already imported
either, so we will correct the wiki-page to not mention anything about

It means there will always be one and only one node containing only
address tags or one way with only address tags and building-tag set.
There could be POIs (amenity,shop) containing addr:*-tags in addition
to this "one and only one". This is to avoid removing address
information already stored in existing POIs which might be used by
people. There are automatic scripts to check that there is only one
object with only address tags.

The original suggestion in the Norwegian OSM community was to follow
the practice in Denmark where addresses on other things than nodes are
not allowed. But since some (in Norway) have opposed this - and still
want to keep addresses on buildings, this has been changed to a
suggestion for those who want to spend time on it and not a
requirement. This can of course be reconsidered and the suggestion
removed all together.

This is a very good question (If I understand the question correctly).
Considering that people started pulling in nodes from this dataset
into OSM already a year ago in a manual process, and that these
addresses already have become a "vital" part interleaved with other
data, it's not so easy to remove the nodes from the municipalities
already imported. It's of course possible - but nobody in the
norwegian community would be happy about it. Hopefully this is just a
theoretical question.

Best regards,
