Danish

The construction in Danish seems to work a bit differently, requiring hvor "where": Men det kunne også blive i Bretagne, hvor hun har et hus.

[jnivre]

Since we generally favor an argument or modifier relation, rather than "mark", for the element introducing a relative clause, I don't think "mark" should be used in these cases.

[ftyers]

@jnivre that sounds good to me, @liljao can this be changed in Norwegian ? (also, note that Swedish has acl:relcl here where Norwegian has plain acl).
