The International Standards Organization (ISO) has published the Technical Corrigendum 2 for PDF/A-1. According to the ISO documentation, this Technical Corrigendum contains corrections that were discussed by a number of technical experts and at the ISO/TC 171/SC 2 meeting held in Orlando, FL (USA) in October 2009. The ISO adds that these corrections are based on issues that have been raised by numerous implementers of ISO 19005-1:2005 since its publication (and its associated Technical Corrigendum 1 in 2006). In addition, certain changes made to ISO 19005-2:2011 have been incorporated where appropriate. The download is free with website registration.
