I have just released revision 0.3 (Proposal - Working Draft) of the
PDF/is specification (formerly "PDFax"). The new version is available
here "ftp://ftp.pwg.org/pub/pwg/QUALDOCS/pwg-ifx-pdfis-latest.pdf" and
on the web site.

Major changes for this release:
- Format name changed to "PDF/is" from "PDFax". 'IS' stands for
'Image-Streamable'.
- All new PDF name extension keywords are now registered with the Adobe
PDF Name Registry as 'Class 2' names to avoid conflicts.
- 'Banding' of images on a page was rejected as this concept violates
the Adobe Imaging Model (See [pdf] Section 2.1.2).
- Format was modified to be compliant with PDF/X-3 specification.
- 'cm' operator calculations were incorrect and incomplete. These are
now fixed.
- Calculation to determine image resolution is now part of
specification.
- Profile letters and numbers have now been replaced with readable
strings to aid in comprehension.
- Various minor document cleanup.

A new version of IPPFAX will be coming soon.

-Rick
