Hi Peter,
good to know that my assumption was wrong.  I must admit that I only
compiled the testfiles shipped with pdfx.sty with pdfTeX and sent the
PDF files to two online PDFA validators.  

There were a few error messages about metadata and color profiles.
Instead of continuing with pdfTeX or LuaTeX, I'm playing with
Ghostscript now because it seems that I can create a valid PDFA much
easier this way.  And since I have to implement PDFA in Lua, it's
quite helpful to have a valid PDFA file so that I can see how it is
constructed.  The main problem is that I'm not familiar with color
management at all.

Unfortunately everything is time-consuming.  One PDFA validator has a
nice web interface but the other one accepts files by email and sends
its results as email attachments.  The latter is more picky, hence I
can't avoid it though it's quite inconvenient.

Anyway, it's good to know that LuaTeX supports ISO-19005 compliant
linebreaks already, all the other problems can be solved at Lua level.
Hopefully. 

Regards,
  Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
