Country-based element selection for ElementFilterExpression

[burrscurr]

When looking into how to implement #5667 I thought that it would be cool to select (or exclude) elements based on the country they are in, for example like this: nodes with traffic_sign=city_limit in DE or nodes with traffic_sign=city_limit not in PL. Would an extension like this be helpful? I think this could make it easier to adjust quests to country-specific conditions besides the more coarse option to enable/disable a quest in its entirety.

Do you have something like that in mind:

StreetComplete/app/src/main/java/de/westnordost/streetcomplete/quests/accepts_cash/AddAcceptsCash.kt

Lines 57 to 62 in 918050a

	override val enabledInCountries = NoCountriesExcept(
	"FI", // https://github.com/streetcomplete/StreetComplete/issues/5500
	"GB", // https://github.com/streetcomplete/StreetComplete/issues/4517
	"SE",
	"NL", // https://github.com/streetcomplete/StreetComplete/issues/4826
	)

Note "adjust quests to country-specific conditions besides the more coarse option to enable/disable a quest in its entirety."

• I thought that having such a feature in element selection parser would be a good idea too, but see Allow for Country of current Quest to be visible and checked against in elementFilter #4528

I'd rather not extend the element filter syntax like that. I don't see a reason why one wouldn't highlight the city limit sign in any country. If it is irrelevant for the speed limit in some countries, then the hightlighted element can just be ignored by users.

If there are no objections to highlighting all city limit signs I'm happy to implement it this way.

Edit: #5675
