libreoffice converstion of egistrymodifications.xcu user items to systemwide xml registry share

Hello everybody,

I am trying to convert changes to 
/home/$USER/.config/libreoffice/4/user/registrymodifications.xcu into 
systemwide configuration for users that start libreoffice for the first 
time under linux with systemwide settings.

I tried placing a xml file in 
/usr/lib/libreoffice/share/registry/registrymodifications-system-wide.xcu 
but I can not seem to get the syntax right.

I found the schema here, not sure how to use them to create my own 
configuration: 
https://cgit.freedesktop.org/libreoffice/core/tree/officecfg/registry/schema/org/openoffice

Can somebody give me example for a system wide registrymodificaton or 
look at the attachments and help me out with these few settings.

Kind regards and best wishes,
