Detect missing railway=level_crossing

[naoliv]

Could JOSM detect (and autofix, if possible), missing railway=level_crossing (railway intersecting with highway != footway|path) and railway=crossing (railway intersecting with highway = footway|path)?

JOSM currently warns "Crossing ways" when a railway and a highway cross …

I can't see anything with the attached example.
Note that I am talking about the intersection node (it misses a railway=level_crossing)

[simon04]

Confirmed. I tested without a the node at the crossing …

An unfinished MapCSS test (which matches every node if a way has both highway and railway set)

node[railway!=level_crossing][has_parent_tag("highway")][not(regexp_test("footway|path", parent_tag("highway")))][has_parent_tag("railway")] {
  throwWarning: tr("highway/railway crossing without {0}", "{0.tag}");
  fixAdd: "railway=level_crossing";
}

node[railway!=crossing][has_parent_tag("highway")][regexp_test("footway|path", parent_tag("highway"))][has_parent_tag("railway")] {
  throwWarning: tr("highway/railway crossing without {0}", "{0.tag}");
  fixAdd: "railway=crossing";
}

With the following MapCSS function added.
