Thanks for this information. The difference between extended and
strict allows for confusion to occur. In the option
"load/save,general", there is no option "strict standard", only 10/11,
12, 12extended.

How can font-embed occur if affected by licence restrictions on a font
(e.g. font x is licenced to be used only on gpl systems)?

So how are non-standard elements treated when ignored?

It seems safer to select either odf 10/11 or 12"strict". Is there a
definitive list of these LO 12extended "features" so that users can
decide if it beneficial to use them, or revert to standard odf?
