The goal is to manage LibreOffice configuration centrally
in the enterprise. In Windows Server environment using
Group Policies is a common solution for configuration
management. Therefore it is required that LibreOffice can
read configuration data from Windows registry, too.

Windows registry is another configuration layer on the
top of normal xml based configuration.

For example the following registry setting:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
"Value"="Example Corp."
"Final"=dword:00000001
becomes the following in configuration:
<item oor:path="/org.openoffice.UserProfile/Data">
    <prop oor:name="o" oor:finalized="true">
        <value>Example Corp.</value>
    </prop>
</item>
