Currently the xUnit plugin does not accept some test reports generated by the test framework of Boost 1.63. The problem is that these reports may contain a "Message" element as child of a "TestSuite" element (see attached file "boost_test_report.xml") which will not pass the validation by the current "boosttest-1.5.0.xsd" file of the plugin. I have also attached a modified xsd file which will accept the attached report format.
