man setxkbmap and https://www.x.org/releases/X11R7.5/doc/input/XKB-Config.html

• XkbVariant - variant(s) of the layout you intend to use
• The XkbVariant option has been left out. That means the default variant named "basic" is loaded.
• equivalency between "00-keyboard.conf" config file and "setxkbmap" command
