If I understand this correctly...

Docs are generated from GPL source.  We want the generated docs to be 
covered by some other copyright.

Solution, have the FSF officially bless this and then document it as a 
blessed transformation.

Essentially what the FSF blesses is the idea that certain bits of the 
GPL source are also under another license (FDL), and that one is 
permitted to so convert these bits into stand alone content (a set of 
html pages for example), and that content is FDL covered.

Informally, I think that this really is a non-issue, but, because it 
touches legal things, it does really need to be discussed with the FSF 
and proposed and accepted and documented for all to understand.  Thanks 
for bringing it up.
