The first step in a path expression can be any expression that returns a
node-set. The value of $node is a node-set. In XPath 2.0, subsequent
steps can also be expressions that return a node-set. But they can't be
expressions that return strings: the value of $branch is not a node-set,
it is a string.

XPath variables represent values, they aren't macros that represent
parts of an expression.
