Add "natural and landuse of the same type should not cross each other "

[mkoniecz]

as explained in #9507 natural and landuse may cross each other but on the other hand landuse=forest should not cross other landuse=forest (also landuse=residential with landuse=residential) etc.

I tried this but it doesn't work, is there a way to implement this with current syntax or do we need another evolution ?

area:closed:areaStyle[natural] ⧉ area:closed:areaStyle[natural = *{0.key}] {
  throwWarning: tr("Overlapping Identical Natural Areas");
}

area:closed:areaStyle[landuse] ⧉ area:closed:areaStyle[landuse = *{0.key}] {
  throwWarning: tr("Overlapping Identical Landuses");
}

In 6680/josm:

fix #9556 - Validator: add "natural and landuse of the same type should not cross each other"

The current spatial selectors are evaluated from right to left. The right one is considered to be the parent object (this naming originates from normal child/parent selectors). Thus, using parent_tag on the left part gives access to corresponding tag of the right object. {0.key} is not known to the MapCSS part, but is only inserted after a successful match by the tag checking part.

Ok thanks :) this syntax is awesome, need just some time to master it :)
