Hmm. I do not think a definition of freedom needs depend on
such a demarcation, but perhaps I could be educated.

Could you explain to me how this is radically different from
internationalization of computer programs? Let me work along with
your example, just to make a point. I wrote up a a program with its
text strings in English, and it was translated into Polish by my
Now, since the program is distributed under a free license,
Vlad continued to make improvements, even though I was busy, and he
wrote up the docs in his native tongue, Polish. Since I have little
time, the code is hacked on by Ivan, and the primary source of the
program strings is now polish.

Why is the compiled form relevant? Which is the currently
preferred form to apply changes to? If it is the word file, then sure,
the word file is the preferred form to distribute (and other forms
are created by converters that take word docs and write out html,
xml, rtf, pdf, etc).
Why this need to figure out what the compiled form is? You
distribute the file format which is the primary source of creating
the content, be it code, data, or documentation -- works for all
manner of software, be it programs or documentation.

Umm, I suppose one could automate the translation f program
strings into another language, (witness the babel fish), though
perhaps poorly, so the parallel holds.

Given UML, and some higher level programming languages peopel
are flirting with, it may be feasible to automatically generate large
protions of code required to implement complex systems in multiple
languages from the abstract description of the models, and contracts,
of the program being written. Of course, one still needs to convert
manually the guts of the code, but let us not insist that code
translation between languages is infeasible (no computer needs more
than 640KB memory). But this is a digression.

You are given free software, and allowed to modify it as you
wish, under the same terms as the original license. Pray tell, how
does it not cover format changes? The DFSG does indeed require that
this freedom be provided to users of documentation.

Is a program free if it requires a non free compiler to
compile? Or a non free vortual machine to interpret it? Why should
documentation be treated differently?

Is a program free if a non free compiler compiles it besat,
but a free compiler is available that does a "reasonable" job?

Quite. How far does reasonable go? This is really important
when it comes to kaffe, gcj, and j2sdk. Why is documentation any
Frankly, I am puzzled: so far, every example you have given
immediately brings to mind an almost exact equivalent from the
program code side of software; and you do not seem to have made your
case that software is indeed different.
When the government bureau's remedies don't match your problem, you
modify the problem, not the remedy.
