Yep -- Nathaniel's right--this is bad wording on our part. Instead of saying "...in the <unchecked/> element" it should have said something like, "...with the <unchecked/> element" or "...using the <unchecked/> element." So, it wasn't meant to be a trick question about whether you knew that <unchecked/> is technically an empty tag. It was just supposed to
test whether you knew about <unchecked/> and its relationship to method permissions.
Nathaniel, just wanted to say that you're awesome.
cheers,
Kathy
