Dimitre:
Thank you for your comment. We discussed this on the 12/2/2003 telcon
and decided not to change the name of the function. "empty" is as
imprecise a word as "exists" and it did not seem that a change in the
name of the function would benefit our users.
All the best, Ashok

Subject: [F&O] 15.1.8 fn:exists
There are two issues with this function:
1. The function name does not accurately reflect its semantic - it
does
not provide an answer if a sequence exists, but if a sequence
is non-empty.
Because
not(empty($seq)) = exists($seq)
a better name for this function would be notEmpty() or nonEmpty()
2. The example in 15.1.8.1 is incorrect:
"fn:exists($seq) returns true."
The above statement is true only if $seq is non-empty and $seq has not
been defined. One can incorrectly deduce that the function returns true
for any sequence.
