Yes, I'm pretty sure they're incompatible, actually.
Dual licensing should be possible. Just change the submission notice to say that users agree that content can be used under both the terms of the FDL and the CC Share Alike license.
Well, several of us have analyzed this carefully, and I don't agree. Dual licensing doesn't really help much, and actually would tend to invite disastrous complexities.
Here's the problem: there's tons of GNU FDL only content in Wikipedia. Anyone can take that content and modify/redistribute it *under the GNU/FDL*. But they can't take the content and modify/redistribute it *under the CC/ATT-SA*, even though the licenses are very similar in spirit.
A writes an article and releases under GNU FDL. If B tries to dual license it and distribute to C, then B is purporting to give rights to C that A never authorized. (In particular, the ATT-SA drops several specific requirements of the GNU FDL.)
