As-is to an extent that avoids lying, yes, but not to the extent that fixes an invariant section. For example, if an original (by Dr. X) said "Churchill was a pompous windbag that everybody hated.", then I might write "Dr. X wrote "Churchill was a pompous windbag".", which is fair use in the context of an encyclopaedia article, and release that under the FDL. Then a derivative FDL encyclopaedia should be able to shorten it to "Dr. X called Churchill "a pompous windbag".", but that wouldn't be possible if my FDL release classified the quotation as an invariant section.
*lightbulb*!
Sorry. Now I follow you.
