I'd file a bug against that documentation (link?). Because the zoom and 
minimize boxes certainly still work, the path popup when command-clicking the 
window title too, as does resizing a window using the grow box or the window 
edges, depending on which MacOS version you're running under.

Try it: Open an RTF file in TextEdit, choose "Make Plain Text" from the 
"Format" menu, then try what you can do to the window.

That said, I doubt there's any supported (not to mention documented) way to 
make the close box work while a sheet is up. If someone finds out, I'd love to 
know how I can do that. I have a custom window where I'd want to achieve 
standard behaviour by making my (fake) zoom and minimize boxes work while a 
sheet is up.
