Philip,

It this case, "recent" means "too high a version". Adobe has kept adding
"fancy" features to the PDF spec since version 1.3 or 1.4, which are not
print-related, such as JavaScript, embedded Flash, forms etc. Many
non-Adobe PDF interpreters or parses only support the older PDF
versions. I'm not sure which is the highest version of PDF that XeTeX
supports, but my guess it'd be 1.3 or 1.4. But that's also a popular
practice by some print publishers. Recently I had to submit a print ad
to a magazine, and their requirement was that it should be PDF version
no higher than 1.4.

Best,
Adam
