I've been having trouble figuring out how to export with styles in Windows (so I can use docx to plug into inDesign). So I tried what nontroppo suggested.

This is the result in Word's document map:

See a test project that demonstrates this here
I downloaded the project, Unziped it, Opened it. Without touching anything, compiled it as docx using the "ModernPart-Chapter-Scene" Format, and the result was no styles (just font, size, and I assume, color). No document map.
I noted the zip file had a "__MACOSX" folder, so my guess is that this is a Windows bug.
