hi all,
in case you are adding new ODF extension elements or attributes that were not already in TDF `master` branch before April 1st, please use the new "coext" extension namespace instead of "loext".
https://gerrit.collaboraoffice.com/c/core/+/1071
i've also added it to OOXML as i was surprised to find an "loext" in the OOXML filter too.
regards,
michael
