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:
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"
