Again, let's please be more precise.
PDF/A is a strictly conforming _subset_ of PDF/X and
is defined in ISO 19005-1 (September 2005). PDF/A is
the first part of this newer multipart ISO standard.
PDF/X is defined in the multi-part standard ISO 15930.
Quoting from ISO's own article:
"PDF/X: A family of graphic technology standards that
standardize the used of the Adobe PDF for eXchange of
PDF/X-1 (ISO 15930-1): Complete exchange of CMYK data.
PDF/X-2 (ISO 15930-2): Exchange of CMYK and/or colour
managed data where some of the data required for final
output (e.g. fonts, high resolution picture data, etc.)
is uniquely identifed but exchanged separately from the
main body of the data exchange.
PDF/X-3 (ISO 15930-1): Complete exchange of CMYK and/or
colour managed data."
See the full text of this ISO article on PDF/X at:
Now, at the risk of many flames, I'll say that IMHO
no amount of money or power will _ever_ make another
vendor's forthcoming "XPS" format displace the ubiquitous
use for years in the professional prepress/production
industry of PDF/X, nor the commitment of many governments
to the use of PDF/A as their normative archive format.
