If we restrict to just element IDs, and in particular to attaching to the first element with the given id, I think the performance impact becomes pretty close to nil (at least in Gecko). I'm not sure how much of a problem that ends up being in practice, though. > I'm curious what other browser developers think. Could this be done > without significant performance impact? That depends on how much the API is used, right? If it's just a few selector-matching operations per mousemove or whatnot, that's not that bad performance-wise.... until people start writing crazy selectors. -Boris
