The name of the data source object used to access it in a template document.
When the name of the data source object is specified, you can access the data source object and its members in a template document using the name.
When the name of the data source object is None or empty, you can still access members of the data source object in a template document using context object member access (see Template Syntax Reference for more information), but you cannot access the data source object itself.
When passing multiple DataSourceInfo instances to DocumentAssembler, only the name of the first data source object can be None or empty. Names of the remaining instances must be specified and unique.
