- public class FuncDocument
- extends Function2Args
**For advanced use only**
Execute the Doc() function.
When the document function has exactly one argument and the argument
is a node-set, then the result is the union, for each node in the
argument node-set, of the result of calling the document function with
the first argument being the string-value of the node, and the second
argument being a node-set with the node as its only member. When the
document function has two arguments and the first argument is a node-set,
then the result is the union, for each node in the argument node-set,
of the result of calling the document function with the first argument
being the string-value of the node, and with the second argument being
the second argument passed to the document function.
