Indeed, as I said, passage would have seemed less odd than crossing, but 
we won't change that key.
A crossing(=*) is my way of thinking of one too; I have always wondered 
why OSM calls it a highway.
But Osmose just flagged as errors bicycle=yes alone.  It wanted us to 
add network=bicycle.
The reason was that both appear together more than 50 times!!!
So, I think crossing=* would be booked again for contravening people's

You mean a separate highway, don't you?
It allows highway=* and that is something having been tried now.
But Osmose is scolding because I have a way tagged like one of its nodes!!!
Osmose is always hiding and jumping from behind a bush ;-)
Furthermore, security wise, I prefer to make it clear that it's a single

I think I'll have to do as if it's not a Z crossing but a side lane.
BTW, drivers exiting (on the right) have to stop on the Z crossing, 
which is forbidden.
They could at least have painted it on the left side!!!


Thanks for your help.
