I suppose I should worry about this--or actually, since I'm interested in 
producing archival PDFs of linguistic documents, I should worry about PDF/A. 
The wikipedia article about PDF/A (http://en.wikipedia.org/wiki/PDF/A) has a 
section about "establishing conformance," but there are no links to such tools. 
  There is a list here:
     http://www.pdfa.org/2011/08/validating-pdfa/
But those appear to all be commercial tools (although the one at 
http://www.intarsys.de/en/prod/pdfa-live may be good enough for our needs).  And 
a rather old GitHub project to do validation here:
     https://github.com/gbm-bailleul/padaf
A rather long discussion here (despite its having been declared out-of-scope!):
 
http://stackoverflow.com/questions/569129/how-can-i-test-a-pdf-document-if-it-is-pdf-a-compliant

It would be nice if xdvipdfmx had a switch to produce PDF/A (and maybe PDF/X) 
conformant documents.  I don't know how easy that would be; there seem to be a 
lot of considerations.
