Answer 1

The only concern I see over here is that - we won't be able to perform migration operations like import or export xml files into and from SoloLearn for comparison purposes. Otherwise, if we are able to translate xml to tabular formats, would be good enough too. Unsure of how it will be possible to implement it. I believe that even now the data is stored on remote location in xml format itself after we compile code remotely. But that is not visible to end user!
