DSE Merge related exceptions

currently, triggering a conflict resolution on models results in a SAXParseException error dialog. this should be avoided if possible.

org.eclipse.emf.ecore.xmi.XMIException: org.xml.sax.SAXParseExceptionpublicId: platform:/resource/test.project.with.model.project/example.wtspec4m; systemId: platform:/resource/test.project.with.model.project/example.wtspec4m; lineNumber: 7; columnNumber: 2; The content of elements must consist of well-formed character data or markup.
