I don't know about the rest of the world but in France you cannot sell (or give, or transfer in any way) attribution rights, only copyright.

I thought this didn't apply to computer programs, but I looked it up and you're right... In France, authors' moral rights are quite strong.

In the UK, the moral right of attribution exist, but there's a specific exception for computer programs, so that programmers don't have a right to be identified as the author, or as far as I can tell any other moral rights.
