In short, that is the unique name for a bunch of translations for a
particular application or group of related applications. The key point
is that the name of the file in
/usr/share/locale/<LOCALE>/LC_MESSAGES/<DOMAIN>.mo and the call
bindtextdomain ("<DOMAIN>", NULL)
must use the same <DOMAIN> so that libintl can find the mo file.
However, that means that all applications that are installed in
parallel need a distinct domain. Since the whole point of SONAMes is
to allow several different library API versions to be installed in
parallel, every library API (i. e. SONAME) should have an unique
domain, which can be achieved easiest by just appending the SONAME to
the translation domain.
In my test packages I used the following patch:

Compared to the SONAME, changing the translation domain is relatively
uncritical, so if you don't want to change this upstream, I can
maintain this patch for Debian/Ubuntu. However, I heard that some RPM
guys plan a infrastructure similar to mine, and at that point they
will have precisely the same problems :-)
Thanks for considering and have a nice day!
