If the PDF spec's on Adobe's web site then I
haven't been able to
find it yet...
As of 2005-01-30 I found
http://partners.adobe.com/public/developer/en/pdf/PDFReference16.pdf,
and it was there when I checked sometime later this year (I don't have
any record of that date).
I note it's a PDF file, which makes for an amusing checken-and-egg
problem in principle. :-)
