PDF/A-2b (ISO 19005-2), archival with reliable visual appearance.

PDF/A-1b (ISO 19005-1), based on PDF 1.4: written with a classic cross-reference table and no object streams. Transparency, JPEG 2000, optional content and embedded files are not allowed, and subset CID fonts get the CIDSet stream the part requires.
