The DISS Diagnostic Trees are XML files that define a particular issue scope and various diagnostic information pertaining to that scope. Diagnostic Trees not only define commands like sound tests, and how to gather information, but also how to format that information in the report. Furthermore diagnostic trees are able to link to one another and inherit formatting and diagnostic commands from one another.
