I'm surprised no one noticed that before. The spec is a little
ambiguous, isn't it? But the intended effect is the empty string,
if the original string consists of nothing but whitespace characters.
This case should probably be clarified in XPath 2.0's functions
( http://www.w3.org/TR/xquery-operators/#func-normalize-space )

test="string() and not(normalize-space())"

would tell you if the string's not empty and that it is empty
when its whitespace is normalized.
