This is excellent news! Thank you for your effort. > #1 > What is the name of this primitive please? \mdfivesum, for consistency with other XeTeX primitives where the initial "pdf" has been stripped (not my choice). See http://tug.org/pipermail/xetex/2015-July/026072.html > Luatex and pdftex have the \pdfminorversion primitive to set the required PDF > version.

(default is PDF 1.5 but PDX/x-1a:2003 requires PDF 1.4). None has been imagined, indeed. It would be good to put our heads together to think about an interface allowing XeTeX and xdvipdfmx to better communicate with each other, but I'm not really up for it right now. > This "-z 0" is needed because the XMP Metadata packet must *not* > be compressed, but must remain readable as plain text, in UTF-8 encoding. > With "-z 1" or higher, the Metadata is compressed. > > With texlive-sr.pdf the filesize difference is enormous: > ~798 kb with "-z 1" > ~10.4 Mb with "-z 0" That is significant indeed. > I've been unable to find a way to specify that parts of the generated PDF > be uncompressed while other parts can be. We don't have one at the moment. How does pdfTeX deal with that?
