If no version is specified, then there is no problem:
- FUTURE REVISIONS OF THIS LICENSE:
"If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation."
The only potential problem is if there are projects saying "license under GFDL v1.2 [only]".
I think this is important, thank you Brianna.
I think it is absolutely untrue that any of our projects is licensed under conditions that do not allow "or any later version". In any event, this has never been approved by the board or, as far as I know, by any community.
There have been, in the past, some discussions by people who are not lawyers about questions of whether "or any later version" clauses are possibly problematic in some legal jurisdictions. I am unaware of any lawyer for the Foundation, for FSF, or for CC (who has the most international set of lawyers working on their licenses) ever actually making that claim. (But it is possible that someone has, I am just unaware of it.)
