Content type/UTI to open CSV in app

Question

How can I write the CFBundleDocumentTypes property of my .plist file, to allow the app to be displayed in the "Open in..." dialog in the other applications?

That's mine, but it doesn't work

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array/>
        <key>CFBundleTypeName</key>
        <string>Readings</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>text.csv</string>
        </array>
    </dict>
</array>
