The values proposed in the tables are pertinent to Portuguese. However, in order to cope with typical aspects of politeness reflected in verbal inflection, the GENELEX model built for the Portuguese language made a particular use of this attribute -- instead of a feature Person, a decomposition of this is used: Person-deixis and Person-conc.
