--- Comment #1 from Michael Kay <mike@saxonica.com> ---
The main reason for the omission, I think, is the difficulty of doing it with
deterministic functional semantics. 

See also bug #13494 and bug #13747.

The EXSLT library attempts to tackle the requirement with a deterministic
function that generates a number that is a pseudo-random function of a supplied
seed:
