Tested on OE 4.2rc (the one shipped with eZ publish 3.9rc1)
While looking into eZ publish 3.9rc1 I discovered that OE has the following settings in extension/ezdhtml/settings/site.ini.append:
However, these settings does not exist by default in eZ publish (in settings/site.ini). Therefore, these settings is OE spesific and should probably be located in a different .ini file?
Also, these settings are not documented anywere (all settings in settings/site.ini is documented in the .ini file itself)
