[Tagging] highway=crossing used on ways

As I used it

On a node:
highway=crossing
This only say not so much, it could be also unmarked,  crossing with a 
value.
Mostly I tag a crossing_ref.

Footway:
On a way:
highway=footway
footway=crossing
crossing=uncontrolled or else, this is for the whole crossing.
(crossing=island can not be used, you can only use crossing once)
if there is in the middle a crossing island, that little part, where
pedestrian could wait, often there is a traffic light for pedestrian,
tag crossing:island=yes
but on this little part there can not be a crossing_ref=zebra

That part as a polygon area
area:highway=footway
cycleway=crossing
crossing=uncontrolled
crossing:island=yes
The last 3 tags could be retrieved from the way!

Cycleway:
On a way:
highway=cycleway
crossing=uncontrolled or else
if there is in the middle a crossing island, that little part, where cyclist
could wait. often there is a traffic light for bicycle ( more wider busy
road),
tag crossing:island=yes

That part as a polygon area
area:highway=cycleway
cycleway=crossing
crossing=uncontrolled
crossing:island=yes
The last 3 tags could be retrieved from the way!

Path:
highway=path
path=crossing
crossing=uncontrolled or else
if there is in the middle a crossing island, that little part, where
pedestrian could wait. often there is a traffic light for pedestrian,
tag crossing:island=yes
but on this little part there can not be crossing:ref=zebra

That part as a polygon area
area:highway=path
cycleway=crossing
crossing=uncontrolled
crossing:island=yes
The last 3 tags could be retrieved from the way!

The other parts, where you do not walk/ride/drive.
area:highway=traffic_island for the areas.
On the polygon way barrier=kerb  with no area=yes ( this should mean that
the whole island is a kerb, it is not).

I think I found one reason for the mistagged ways. The wiki page
https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dtraffic_island
proposes to use highway=crossing + crossing=island to map a traffic island.
It says that this should be used on nodes but a mapper looking for a
replacement of a landuse tag might miss that.
It also claims to show numbers from taginfo for this combination, but in
fact it shows the numbers for
just crossing=island:
https://taginfo.openstreetmap.org/tags/?key=crossing&value=island
This tag can be used on ways, together with e.g. footway=crossing, but that
would not be used to map the area of the traffic island.

AFAIK taginfo doesn't allow to ask for tag combinations. No idea if this
occurs on other wiki pages, if so,
it is very misleading.

I think the said wiki page should be changed so that highway=crossing is not
mentioned at all.

Gerd
