// Launch Services is somewhat unreliable about registering Apple apps to

// types (instead they claim to handle one or more UTIs). So Launch
// Services must contain logic to translate support for a given UTI into
// support for one or more MIME types, and it doesn't always do this
// correctly. For example DiskImageMounter isn't (by default) registered
// to handle the application/x-apple-diskimage MIME type. See bug 675356.
//
// Apple has also deprecated support for file extensions, and Apple apps
// also don't register to handle them. But for some reason Launch Services
// is (apparently) better about translating support for a given UTI into
// support for one or more file extensions. It's not at all clear why.
