XPages: Add inline CSJS with a Theme

I needed a way to add some inline CSJS to an existing application which affects any XPage, that’s why I did this them with a theme.

<theme extends="webstandard" >

        <script>
            <contents>alert('THEME JS!')</contents>
            <clientSide>true</clientSide>
        </script>
    </resources>

</theme>

The javascript code is added and executed as expected:
