If you are doing remote scanning, you need the xccdf, oval, and cpe files. The 
tool is expecting the content to be sent as a datastream which means that all 
3 are combined into 1 file using a specific format (in the SCAP 1.2 
specification). What this is saying is the content being used to scan with is 
not a data stream and it cannot resolve the objects in order to do a scan.
