If there's a schema that describes the element's type as being a sequence if
integers, then atomizing the element node (which usually happens implicitly)
will automatically yield the content in this form. For example, sum(test) in
your example will be 10.

If there's no schema then you need to do the conversion by hand, e.g. as

for $i in tokenize(test, ' ') return xs:integer($i)
