// We need to be very careful about which UTI type we use.
//
// * In the case of "textual" shares (e.g. web URLs and text snippets), we want to
// coerce the UTI type to kUTTypeURL or kUTTypeText.
// * We want to treat shared files as file attachments. Therefore we do not
// want to treat file URLs like web URLs.
// * UTIs aren't very descriptive (there are far more MIME types than UTI types)
// so in the case of file attachments we try to refine the attachment type
// using the file extension.
