Wikivoyage:Roadmap/Wanted listing attributes

I'd like the following listing attributes to make life a little bit easier.

district=""
The motivation is for listings that belong on a huge city article, rather than the city's district articles. I've been adding listings for embassies on de: and they belong on the Tokyo top-level guide, rather than district level guides, but it'd be easier for readers and travelers if they knew in which district the embassy (or other listing) was located in.
zip code=""
Again, for the huge cities.
bus=""
To indicate the nearest bus stop that serves a listing. The direction="" attribute works, but things can get complicated when trying to format that.
subway=""
To indicate the nearest subway stop that serves a listing. The direction="" attribute works, but things can get complicated when trying to format that.
tram=""
To indicate the nearest tram stop that serves a listing. The direction="" attribute works, but things can get complicated when trying to format that.
