During the preparation of the big import of CLC [1], we have got the two 
codes 1.1.1 (Continuous urban fabric) and 1.1.2 (Discontinuous urban 
fabric). We have mixed them on the same tag landuse=residential.
But perhaps we could have something more accurate for city centers that 
would be near Continuous urban.
That could mean there are apartments shops, garages, banks... But 
without detail (with landuse when there is a shop at the first floor and 
appartments upon it)
This tag would be very used in the French city centre, and maybe we 
could create a tool on osmose [2] to help changing tags.
Why not a landuse=city_centre (according to the English spelling) if it 
fits many situation throughout the world ?
