Latvian: if ~object~ is a Pron and is not modified by a RCl, it is more natural/neutral if it precedes the verb. For this, the lin types of NP and Adv are extended with a boolean field isPron (in addition to the previously introduced isRel field that indicates whether a CN or NP is modified by a RCl).
