ElementType	Gets the type of object submitted as a batch to the data service. (Inherited from DataServiceRequest)
Expression	Represents an expression that contains the query to the data service.
Provider	Represents the query provider instance.
RequestUri	Gets the URI of the request object submitted to a data service. (Inherited from DataServiceRequest)
