 * @short_description: GData authorization domain
 * @stability: Unstable
 * @include: gdata/gdata-authorization-domain.h
 *
 * A #GDataAuthorizationDomain represents a single data domain which a user can authorize libgdata to access. This might be a domain covering the
 * whole of the user's Google Contacts account, for example. Typically, #GDataService<!-- -->s map to #GDataAuthorizationDomains in a one-to-one
 * fashion, though some services (such as #GDataDocumentsService) use multiple authorization domains.
 *
 * The #GDataAuthorizationDomains<!-- -->s used by a service can be retrieved using gdata_service_get_authorization_domains(). The set of domains
 * used by a given service is static and will never change at runtime.
 *
 * #GDataAuthorizationDomain<!-- -->s are used by a #GDataAuthorizer instance to request authorization to interact with data in those domains when
 * first authenticating and authorizing with the online service. Typically, a given #GDataAuthorizer will be passed a set of domains (or a service
 * type, from which it can retrieve the service's set of domains) at construction time, and will use those domains when initially asking the user for
 * authorization and whenever the authorization is refreshed afterwards. It's not expected that the set of domains used by a #GDataAuthorizer will
 * change after construction time.
 *
 * Note that it's not expected that #GDataAuthorizationDomain<!-- -->s will have to be constructed manually. All #GDataService<!-- -->s should provide
 * accessor functions to return instances of all the authorization domains they support.
 *
 * Since: 0.9.0
