How to specify App Store metadata (compatibility and languages)

I need to specify the following in the App store:

• supported languages
• supported devices
• supported OS

I'm guessing it's specified in the app descriptor file under InfoAdditions, but I don't know which property list keys to use.

I'd have thought that Flash Builder would have defaulted to a list which is consistent with the AIR SDK... but for some reason my app is listing devices and OSs that are not supported by AIR.

Any help would be much appreciated.

Thanks,

Osh
