For languages with relatively free constituent order, such as German, Dutch, or the Slavic languages, the combinatorial potential of the language encoded in constituency cannot be mapped straightforwardly onto the word order possibilities of those languages.
the treebanks that have been created for German (NEGRA, Skut et al., 1997;VERBMOBIL, Hinrichs et al., 2000;TIGER, Brants et al., 2002) have relaxed the requirement that constituents have to be contiguous.
