The problem: I believe that it's not possible to dual-license a
derivative work of a work dually licensed under by-sa 1.0 and the GFDL.
Here's my reasoning:


When creating a derivative work of a dual-licensed work, you need to pick a license, say GFDL.

Then you have a derivative work, *only* distributable under GFDL.
The same for BY-SA.

But suppose you create two **identical** derivative works, one under GFDL and one under BY-SA. Then again, downstream users can pick either one of them to create a derivative work, if they know both versions exist.

So I would say you can dual-license such derivative, but you don't have to.
