I agree that it's going to be difficult to get this right, but semi-live templates (if you change it here, it will reflect on all instances, but it you change it here, it won't) seem even more fragile. That's why Hixie made XBL2's templates always-live, I think. But I totally get the need of coming up with a solution that doesn't end up being a memory hog. :DG< > > -Boris >
