===Preservation issues===
PDF/A is the only version of PDF recommended for long-term preservation. According to Library of Congress, "For pragmatic reasons, when PDF/A is mandated, PDF/A-1b is usually acceptable. Full PDF/A-1a compliance, with tagged document structure, is hard to achieve except in a workflow that anticipates that objective from initial document creation." ([http://www.digitalpreservation.gov/formats/fdd/fdd000125.shtml Library of Congress Sustainability of Digital Formats: PDF/A])
