get_spreadsheet_authorization_domain

The AuthorizationDomain for interacting with spreadsheet data.

This will not normally need to be used, as it's automatically used internally by the DocumentsService methods. However, if using the plain Service methods to implement custom queries or requests which libgdata does not support natively, then this domain may be needed to authorize the requests which pertain to the Google Spreadsheets Data API, such as requests to download or upload spreadsheet documents.

The domain never changes, and is interned so that pointer comparison can be used to differentiate it from other authorization domains.
