[pdftex] PDF/X compliance.

I'm very (pleasantly!) surprised by this.

has anyone looked into tabulating what keys are missing and providing 
appropriate default values?

John had originally asked:

and I replied:

and re-Distill.

and Hans asked:

There was a long string of things. I can dig out a .pdf of the test 
report if you want.

Interesting. For those who're curious, this seems to be the link:
http://www.pdfx.info/tools.html
Only Mac / Windows versions though, and apparently all done as 
Acrobat plug-ins?

IME, our printers aren't so accomodating, pre-flighting is strictly 
pass/fail

Cool.
