* #GDataDocumentsFeed is a list of entries (#GDataDocumentsEntry subclasses) returned as the result of a query to a #GDataDocumentsService,
* or given as the input to another operation on the online service.
*
* Each #GDataDocumentsEntry represents a single object on the Google Documents online service, such as a text document, presentation document,
* spreadsheet document or a folder, and the #GDataDocumentsFeed represents a collection of those objects.
*
* Since: 0.4.0
