There is a recurring problem with PDF files produced by either pdftex or luatex in France. Whenever PhD thesis documents are submitted to the French national archives, they have to be validated by some automated process which relies on pdftk (apparently). And files compiled by pdftex/luatex are rejected.

The validation service is at http://facile.cines.fr/

It seems they want PDF/A-1b, since the failure icon links to http://facile.cines.fr/aide/pdf.jsf But the table seems to allow normal PDF 1.5...

Thanks for the link. I uploaded a PDF/A-1b file created with LuaTeX and if a red cross means failure, it failed. This is strange because five other PDF/A-1b validators didn't complain. The xpdf package isn't involved in this case, I wrote PDF/A-1b support entirely in Lua. Only one validator (pdftron), complained about a TrueType font (CharisSIL) "CIDSet in subset font is incomplete" but I reverse-engineered the CIDSet entry and came to the conclusion that everything is compliant with the PDF/A-1b standard. After all, if a particular validator complains and the reason can't be determined, the most reasonable way to proceed is to try to contact the guy who wrote this validator. One can never be sure that validators are perfect. Fabrice, you said:

'No document catalog dictionary' is what you get with the simplest latex file by default.

If you compile with \pdfcompresslevel=0 you'll see that it exists. The question is why the validator can't find it. I suppose that its parser is more fussy than required by the standard.
