One exceptional (unusual) element that I notice in the Office 2010 applications is that there are two tabs in their "fluent" or "ribbon" ux ideas, around Tables, named Design and Layout, which have a bar above them grouping them as "Table tools".
Does the Microsoft Fluent UI guidelines cover cases like this or was this a specific decision made by Microsoft's UX design team? My guess is that Design and Layout are english words that don't connote enough about them being table-related and so the MS OFFICE 2010 UI treats this as a special case:
Is this heading level above the tab names, used anywhere else, either by Microsoft or by others who use the Fluent user interface?
