Maybe a tip that hopefully can save you time in understanding XKB:
Vmods are basically an indirection (as in pointers) to real modifiers
used only in the configuration.  Because real modifiers are limited to 8
and there can be more than 8 conceptional modifier functionalities
(NumLock, Alt, ...) xkeyboard-config can easier determine which real
modifiers share those functionalities.
