A node represents a specific action within an XGEN document.
Generate code for this node.
This method is called when a class containing an XGEN document is compiled.
pTargetClass is the class that contains the XGEN document.
pCode is a stream containing the generated code.
pDocument is the top-level XGEN document object that contains this node.
A subclass will provide an implementation of this method that will generate specific lines of code.
