Let's be clear: you are not passing the node as a parameter, you are passing
its name, represented as a string.

Yes: because the value of the variable is a string, not a node[-set].

So long as you use simple names, you can use the construct
select=*[name()=$ParentNode]".

If you want to construct more complex expressions than simple names, you
need the xx:evaluate() extension function available in several products.
