Of course, there may be other keywords that need a similar treatment. (It seems odd to me that we don't (in effect) generate the production for FunctionQName automatically. It would avoid this kind of problem.) 25006 2 andrew.eisenberg 2009-05-05 21:38:57 +0000 I've done some additional testing, and find that 4 of our keywords cannot be used as variable names. These are "revalidation", "skip", "updating", and "with". 25267 3 jonathan.robie 2009-05-22 21:01:45 +0000 (In reply to comment #2) > I've done some additional testing, and find that 4 of our keywords cannot be > used as variable names.
