No, of course not.
I see what you're saying. We allow people to place certain restrictions and still have a free license. Those restrictions can selectively applied to certain problem domains. But those are restrictions that we allow in all domains. So, in a sense, the license is selectively lifting restrictions in certain domains, which is always ok. <snip> > > > This example seems to indicate that your main problem with the > > > validator is that it seems like a programmatic restriction.

GPL 2c talks about running commands interactively, and that is also strictly for humans. > And, having worked with the LaTeX people for a while now, I think it's > fairly likely that they'll accept wording to that effect. The reason I was pessimistic is because the individual files are not interactive programs. They are interpreted by another program. That program could easily change it's behavior based on what it reads. If, for example, I created a "Trusted LaTeX" that aborted if the validation didn't work, then not allowing people to make modified versions that work in trusted LaTeX is too much of a restriction. But this also touches on one thing that Frank said. He seemed to imply that it doesn't actually matter what program you're using, the Base Format is just the format defined by LaTeX. So if the LaTeX people become evil and later decide to change the format so that you get different behavior with non-validating files, then there has been a retroactive change in the licensing terms. What exactly the format is needs to be nailed down. Regards, Walter Landry [EMAIL PROTECTED]
