Yes, $v1/$v2 is legal in XPath 2.0 provided $v1 and $v2 are both of type
node()* (i.e., node-set, in 1.0 terminology). It's not a very useful
expression, because the result doesn't depend on the value of $v1, but
like $n*0, it's legal.

But this user was after dyn:evaluate(concat( $v1, "/", $v2 )) which is
something quite different, and is NOT available in XPath 2.0.
