[Patch] Flag combination of major highway type (trunk .. residential) and crossing=*

[GerdP]

A way with highway=* + crossing=* should be a minor way, typically footway, cycleway or path.
If the tag crossing=* is used on a major way there is probably a missunderstanding.

I tried this overpass query

[out:xml][timeout:90];
(
  way["crossing"]["highway"]["highway"!="footway"]["highway"!="cycleway"]["highway"!="path"];
);
(._;>;);
out meta;

and got 1510 ways all over the world with 28 different highway tags.
highway=construction and highway=proposed are probably okay, highway=crossing is already flagged in a different test.
Maybe a highway=bridleway is also acceptable? It is often used in a small part of Mexico.

@Klumbumbus: What do you think?

I would exclude highway=pedestrian and crossing=no too. With highway=bridleway excluded too 780 ways remain:

[out:xml][timeout:90];
(
  way["crossing"]["highway"]["highway"!="footway"]["highway"!="cycleway"]["highway"!="path"]["highway"!="construction"]["highway"!="proposed"]["highway"!="crossing"]["highway"!="pedestrian"]["highway"!="bridleway"]["crossing"!="no"];
);
(._;>;);
out meta;

I didn't notice false positives on a quick sample.

And adjusting the text to ...Should be used on a minor highway type or node.

[GerdP]

OK, let's use that.

positive list

With the suggested changes I find these rather confusing messages:

crossing together with highway=alley. Should be used on a minor highway type or a node (14)
crossing together with highway=corridor. Should be used on a minor highway type or a node (12)
crossing together with highway=footway;crossing. Should be used on a minor highway type or a node (1)
crossing together with highway=platform. Should be used on a minor highway type or a node (1)
crossing together with highway=road. Should be used on a minor highway type or a node (1)
crossing together with highway=sidewalks. Should be used on a minor highway type or a node (2)
crossing together with highway=steps. Should be used on a minor highway type or a node (50)
crossing together with highway=traffic_signals. Should be used on a minor highway type or a node (2)
crossing together with highway=yes. Should be used on a minor highway type or a node (1)

We would find all kinds of typos in the highway here. Those should better be reported with a different message.I think it would be better to use a positive list. I copied a statement found in unnecessary.mapcss.
