[F&O] IBM-FO-037: Strange description of fn:unordered

(IBM-FO-037): Section 15.1.14 (fn:unordered): The summary begins "This 
function takes a sequence, or more typically, an expression that evaluates 
to a sequence ...". This implies that a "sequence" is somehow different 
from "an expression that evaluates to a sequence." Actually there is no 
difference. The phrase beginning "or more typically" should be deleted.
