[Libreoffice] [REVIEW] invalid ODF fdo#37390 fdo#44073 fdo#44082

[Michael Stahl]

proposing the following commits for 3.4.5, as they prevent LO from
writing invalid ODF:

with the fix for fdo#44073 LO actually still writes a non-standard
attribute in ODF 1.2 extended mode, but without doing that older OOo/LO
versions would lose data because they don't recognize the standard
attribute that LO writes with the fix.
