Apart from not needing to do it, Mike Kay has suggested that
string-length is relatively expensive because of the need to
sort out surrogate pairs before counting characters.
True, but in Saxon, [string-length(x) = 0] doesn't count the characters, it
simply checks whether the string is empty or not.
That's good to know.
Does it also apply to [string-length(x) eq 0] and just test="string-length(x)" ?
