Testing CD/DVD images "Official"?

[Charles Steinkuehler <charles@steinkuehler.net>]

I'm working on getting setup to become yet another Debian-CD vendor, and 
am wondering about the proper labeling for the testing CD/DVD images 
available from http://cdimage.debian.org/pub/cdimage-testing/

Can images formed from the .jigdo files/templates available here be 
labeled 'official' (assuming MD5 sums match) ie:

  Debian GNU/Linux
  Testing "Sarge"
  Official Snapshot
  alpha Binary-1
  <date>

...or do they need an 'unofficial' moniker?

NOTES:

- I have been unable to find the README.official file referenced by 
README.CD-manufacture in the debian repository.  Perhaps this needs to 
be updated?

- The README file in the debian-cd package (found in a general search to 
find README.official file, which is listed in the debain-cd changelog) 
just says to never use "official" on anything I build myself.

- The images available in the cdimage-testing directory seem to be 
labeled "official" (at least the first one I checked, which was titled: 
'Debian GNU/Linux Testing "Sarge" Official Snapshot alpha Binary-1' in 
the README.txt file ).

I just want to be sure, before I mistakenly label something official 
that's not.
