Looks as if this might need upgrading to handle new 3.0 types (functions,
maps). Which are a bit more difficult to do using "instance of" tests,
because the set of types to test for isn't easily enumerated.
Isn't this expression correct:
$thing instance of function(*) ?
I guess this will fail in XPath 3.0:
$thing instance of map(*)
but this should be OK in XPath 3.1 ... Or not?
Yes - but the challenge is to find out that a map is an instance of
map(xs:string, element(emp)) or whatever, if you want to know what kind of map
you have been given.
