Mistery resolved.. It seems Skyguide removed Basel from the Swiss AIP unfortunaltelly. Let's hope Skyguide will put it back in because I like much more their chart style and the French AIP doesn't have a proper Ground chart..
I heard that they got a lot of protests from Swiss pilots already, so there is some hope that it will come back..
Basel is still a Swiss-French airport, so there is no reason to remove it from the Swiss AIP.
