I fear we are out of luck there. Libreoffice documentation at
https://help.libreoffice.org/3.3/Common/XML_File_Formats#Definition_of_the_XML_formats
says "The schema for the OpenDocument formats can be found on the
www.oasis-open.org web site", i.e., it points to the same nonfree files.

I've also checked the Gentoo app-office/libreoffice-7.0.4.2 package,
and it doesn't install any Relax-NG schemas. It only installs DTDs for
the older OpenOffice.org 1.x format. These are licensed under MPL-2.0.

Maybe it's time to contact OASIS Open and ask them if they would
consider relicensing the Relax-NG schemas. Does somebody know one of the
persons from their committee, because that may be a good place to start:
