Ihe,
Let $s := '' (the empty string)
index-of(('a','b','c'),$s) -> 0
index-of(('a','b','c',''),$s) -> 4
Personally I am happy not to get 0, in either case, when $s is (). :-)
Cheers, Wendell

if I am searching a sequence of strings with index-of having the empty

Why throw an error if the 2nd argument is empty sequence,
irrespective of the type of the first argument.
Isn't 0 the obvious answer here.
