RE: Problem with passing argument to external register

The calling conventions for external functions are implementation-defined,
so things that work with one processor will not necessarily work with
another.

Some processors don't do any type conversions on the supplied arguments: if
the external function in this case is expecting a string, then it might be
better to do the conversion "by hand" by writing
select="foo:bar(string(element/.))".

(Actually, the XPath expression "element/." means exactly the same as
"element" or "./element".)
