investigating bug 37390 revealed: there are 3 attributes which have been added in ODF 1.2, but are written by OOo and LO in any ODF version: style:layout-grid-base-width 20.297 style:layout-grid-snap-to 20.305 style:layout-grid-standard-mode 20.306 additionally, style:layout-grid-snap-to used to be written wrongly as style:layout-grid-snap-to-characters, which does not exist in any ODF spec. there was a supposed fix for the latter problem cited in bug 37390 comment#3 which is bogus as far as i can tell.
how to get these attributes written at all: 1. Tools->Options, Language Settings->Languages, check "Enabled for Asian languages" 2. Tools->Options, LibreOffice Writer->General, uncheck "Use square page mode for text grid" 3. Format->Page, TextGrid tab, select "Grid (lines and characters"
