Use this list to identify each section in the preceding code:

1	The `Registration` element. For more information, see Working with the Registration Element.
2	The `Metadata` element specifies whether an input data source is required, defines the roles for columns in the input data source and any options that are required for the task to run. For more information, see Working with the Metadata Element.
3	The `UI` element specifies the layout of the task in the user interface. For more information, see Working with the UI Element.
4	The `Dependencies` element specifies the options that rely on one another in order for the task to work. For more information, see Working with the Dependencies Element.
5	The `Code Template` element generates the SAS code for the task. For more information, see Understanding the Code Template.
