@redstarfish Unfortunately that's risky as they're likely going to open it in word, as word intentionally implements ODT extremely poorly and not to spec (I observed a valid .odf presentation being displayed as white pages when opened with powerpoint previously for example).

The reason it's in that state is because some governments at least had enough backbone to tell them that their software must support ODF or it's being barred from use in the government, but they unfortunately didn't follow up.
