 * This operation checks the Item to make sure that by default it offers two actions, one for writing the Form to XML and another for writing the Entries in the Form as a set of key-value pairs. It also makes sure that the Form is written to these two file types if the Item is so directed. It also makes sure that processing a disabled Item fails. Finally, it pulls the output file handle from the Item and makes sure that the default name of the file is set according to the default in the class documentation.
