, because some elements must be raised to the functional head. For instance, in English, the negation is clearly borne by the auxiliary (she has not slept) because an auxiliary must always be present in case of negation

. Yet, For instance the xcomp relation in French can correspond to two different SUD relations for similar surface forms: il rêve de venir['he dreams of coming'] commutes with il rêve de ça, some specific cases it is not possible to recover the SUD relation corresponding to the UD relation
