I see (there are a lot of specs to read ...).
1.
I think the example in the spec can confuse.
Why use
fn:tokenize("abba", ".?") returns ("a", "b", "b", "a")
and not (add)
fn:tokenize("abba", "") returns ("a", "b", "b", "a")
?
2.
What should
fn:tokenize("abba", ".")
return?
(Not sure if it's ("","","","",""))
Perhaps it would be a useful example.
3.
You also might want to consider adding an example where the pattern
matches something in the input and an empty sequence is returned, if
there are such cases.
