The feature to attach files to a PDF was specified in PDF-1.3 for the first time. See table 169, item "FileAttachments" on page 390 of the Adobe version of the PDF-1.7 spec (filename "PDF32000_2008.pdf"). > Believe our Poppler integration is capable of generating that level of PDF, > but suspect it would would require a lot of work. I do not think so. It should be no more difficult than the current ("proprietary") implementation that is used by OpenOffice and LibreOffice. (There may be other arguments which could be made in favor of keeping it as it is, and make sure no other application could extract the embedded ODT source file. But I haven't heard any so far...) > However, other than this issue of reworking our Hybrid PDF, more pressing > compliance issues of producing accessible PDF/A-1a and PDF/UA (ISO 14289-1)[ > bug 45636 ] probably already require a more complete implementation of ISO > 32000-1 and production of PDF 1.7 level documents. * PDF/UA: Nes, that requires support for PDF-1.7. * PDF/A-1a: No PDF/A-1b (basic) and /A1-a (advanced) both even *forbid* to use any new features beyond PDF-1.4 and up to -1.7. They *require* limitation to PDF-1.4 features (and have a few other feature requirements and prohibition of features). However, to produce a PDF/UA does not require to support *ALL* features which have been introduced and defined in between and up to 1.4 and 1.7. It is just so that if you want to make a compliant PDF/UA, you'll have to support *some* of the new features, which in turn means you have to declare it as a PDF-1.7 file. -- You are receiving this mail because: You are the assignee for the bug.
