please review:
I've changed node/3697276720
highway=Information to
traffic_sign=Children on the way
If that is an official traffic_sign, please try
to find its code:
traffic_sign=*

thanks for the feedback.
When it is not a highway then it should not have that tag or maybe highway=abandoned if you think that you want to keep some kind of history.
I'd prefer to remove the way.

please review way/161613822 (Jåttåflaten):
highway=closed-unclassified is rarely used.
Alternatives: closed,dismantled,abandoned,construction

please review way/96211042:
the tag highway=closed-footway
is rarely used.
Maybe highway=dismantled or highway=construction matches?

please review way/52987007:
what might highway=closed mean?
Is there a barrier? Or maybe access=no?
Or highway=abandoned?

please review way/6788771:
what might highway=closed mean?
Is there a barrier? Or maybe access=no?
Or highway=abandoned?

please review:
I've changed two ways from
highway=close to highway=residential
changeset/34841639
If highway=close was intended, please describe what it means

please review way/305708560:
What does highway=close
mean? Something like access=no ?
Or maybe highway=abandoned?
way/305708560

Bitte prüfen:
Weg 184019745
Ist das eine Stadtmauer
(historic=citywalls bzw. barrier=city_wall)
oder ein Stadttor
(historic=city_gate)
Evtl. die Linie splitten.
Ein highway=citywalls ist es bestimmt nicht.

please review:
what is meant with the tags on way/260103514
building=yes
highway=checkpoint
The tag highway=checkpoint
is sometimes used on nodes of highways.

please review:
I've changed the rarely used tag
highway=changed to highway=dismantled
changeset/34841047

I see. Is it possible to use them in JOSM as well ?

please review:
most of the way/361786049 is not visible
in Bing or Mapbox. Where did you find it?
