Oh, I will explain:

We can make two things: 
1.) Description-XX file

  In this file are only the Packagname and the Description (and maybe
  the version), like:
   !Package: foo
   !Description: trans of bar of foo
   ! trans of first line
   !
   !Package: foo2
   !Description: trans of headline of foo2
   ! trans of first section of foo2

  You see this file will not have the orignal description. Apt must
  combine this file with the normal Packages file and make with the
  orignal description of the Packages file a .po file.

  (The .po file must have the orignal description.)

2.) Description-XX.po file

  This is a normal po file. This File have the orignal description
  with the translation, like:
   !msgid "bar of foo\n"
   ! "first line"
   !msgstr "trans of bar of foo\n"
   ! "trans of first line"
   !
   !msgid "headline of foo2\n"
   ! "first section of foo2"
   !msstr "trans of headline of foo2\n"
   ! "trans of first section of foo2"

  You see this file has the double size. But the client must not
  generate the .po file. It must only copy this file in the right
  location. 

You understand it now?

yes, I make this with the ddts. But gettext don't work like this. If
you use gettext (like other programs), you must have a .po file, make
a .mo with this file and only use it. 

You can use your own way (like checksum, etc.) and don't use gettext.
But now you must re-inventing the wheel, with all gettext features.

And in Descriptions-XX we don't need checksum, we have the package
name and maybe the version. With this we can assign the translation to
the orignal description.

If we use my proposal, the information in control.tar.gz will only
used by dpkg --info and from katie to produce the Description-XX[.po]
file. 

All other outputs use gettext and no special files from dpkg, control,
etc.
