</span>As far as I remember from a talk at TUG 2015, the packages used to<br>
produce PDF/A using pdftex were extended to work with LuaTeX (perhaps<br>
using newer versions of the package) and one difficulty they faced<br>
with XeTeX was the lack of a way to compute MD5 sums. Now IIRC a<br>
primitive was very recently added to XeTeX for MD5 sums. So perhaps<br>
it wouldn't be too much work to port the package to XeTeX.<br></blockquote><div><br></div><div>Luatex and pdftex have the \pdfminorversion primitive to set the required PDF version. AFAIK there is no way how XeTeX could communicate such a requirement to xdvipdfmx. The only way is to call xelatex -no-pdf ... and xdvipdfmx -V4 ... (default is PDF 1.5 but PDX/x-1a:2003 requires PDF 1.4). <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
