MS Office XP

This is probably exactly the same as installing 2003, but:

<package
        id="office"
        name="Microsoft Office XP"
        revision="1"
        reboot="false"
        priority="1">
        <check type="uninstall" condition="exists" path="Microsoft Office XP Professional" />
        <install cmd='%SOFTWARE%\office\setup.exe /qb /l* %temp%\office10.txt COMPANYNAME="MYCOMPANY"' />
        <remove cmd='%SOFTWARE%\office\setup.exe /qb /x' />
</package>
