Will test true only if you are on the <foo> element (it has a parent, the 
root; but that parent is not an element and fails a parent::* test)

Will test true for any element node, the <foo> element or any other.

I hope this is enough: it's a bit tough for me to understand your exact use 
case.

Using the other suggested approach, testing node-identity with 
generate-id(), you could say

generate-id()=generate-id(/*)

which will also test true only for the <foo> node (since it's the only 
element child of the root).

Cheers,
Wendell
