ESS2 Regional documentation for Italy

Incorrect documentation for the variable REGIONIT for Italy has been presented in the "ESS2 - 2004 Documentation Report, ed. 3.1". However, the correct codes are used in the data file, which is also identical to the ones used in ESS round 1. The following codes were wrong in the documentation report and the correct ones are; Piemonte=1, Valle d'Aosta=2, Lombardia=3, Trentino-Alto Adige=4, Friuli-Venezia Giulia=6, Liguria=7, Umbria=10, Marche=11, Campania=15, Puglia=16, Basilicata=17. The Documentation Report will be corrected in subsequent editions.
