 The save output option will store the output xml document. The xml mode's drawback is
 that it doesn't do any quality checks that all elements and values actually match the
 original document.
-
-# JSON Mode
-
-Each test case will generate the models for the schema document, parse the xml instance
-document and serialize it to json, parse the json document and compare the initial
-python object to the object after the roundtrip conversion.

-Results: **22** failed, **14650** passed, **2** warnings

-Most of the failures involve test cases with complex instances with wildcards and
-derived types.
-
-# XML Mode
-
-Each test case will generate the models directly from the xml instance documents, parse
-the xml instance document and serialize it back to xml checking that the output is still
-valid.
