[F&O] IBM-FO-022: Which function backs up "eq" on strings?

(IBM-FO-022): Section 7.3.2 says that fn:compare() with the second 
signature backs up "eq" and other value comparisons on strings. Actually, 
the first signature is used (since the value comparison operators have no 
way to specify a non-default collation).
