XML Schema Unit Unit (SUT) is an open source framework for unit testing XML Schema. It helps promote XML data exchange by ensuring schema documents are complete and accurate.
Martin Szugat (hampti@users.sourceforge.net) has written an article on XML Schema in the German language dot.net magazine 6.05 (http://www.dotnet-magazin.de/) and includes a mention of SUT. The article is available at http://sut.sourceforge.net/DM_6.05_110-113.pdf.
Martin also points out that SUT is being used for his bioschemas initiative (http://schemas.bioservices.net) and the ProML project (http://www.bio.ifi.lmu.de/2005/proml). He hopes to publish a scientific paper about ProML in the next months.
