The FSF's discussion of invariant sections mentions making the GNU  
Manifesto invariant when included in manuals...

How can this be enforced downstream, in derivatives of the FDL work?

Yes, this (or invariant sections) might work well for keeping  
attribution and the attribution URL as well.

[But FDL is still so very different from BY-SA. How do I make an FDL  
derivative of a CC-BY-SA poem into a song, or a story into a movie?  
One of the CC licenses' strongest points is that they are designed to  
allow deriving works across media. If I derive FDL work from GPL work  
I'm locking the work pretty much to a textual format, breaking this  
principle as well.]
