I stand corrected. With the real world performance difference, I'd prefer that getElementsByTagName() and getElementById() were supported for fragments, too. Pros: - Better optimized performance - Making API more similar to Document Cons: - Two extra methods in the namespace (however, nobody sane will use neither of the old method names for anything else so this can be ignored) -- Mikko
