Apply the function serially over the given node sets.
In iteration i, the function is passed N parameters
where N is the number of argument node sets. Each
parameter is a node set of size 1, whose node is
the ith node of the corresponding argument node set.
The return value is a node set consisting of a series
of result-tree nodes, each of which is a text node
whose value is the string value of the result of the
ith function invocation.
Warning: this function uses the implied ordering of the node set
Based on its implementation as a Python list. But in reality
There is no reliable ordering of XPath node sets.
In other words, this function is voodoo.
