Why? because in the intervening time after the last time you tried and 
the next, something happened to change the answer. Such as, "I tested 
the availability of <x> and since it wasn't there I loaded the necessary 
file, and now it *is* there."

Well, it doesn't say "allowed to treat *a string* as unknown," it says 
"allowed to treat *an attribute* as unknown." In other words, it is 
perfectly legal to refuse to answer the question.
