This code should work provided that:

(a) you are running an XSLT 2.0 schema-aware processor

(b) your source document has been validated against a schema that declares
the type of the element to be an integer.

(c) you have bound "xs" to the XML Schema namespace.

To know which of those conditions you haven't met, I would want to see the
error message...
