Tokenization, as I under stand the usage here, represents compression
using a predefined dictionary of codes and values. No different than
using a compression technique such as LZW with a predefined standard
dictionary. The key for either approach is the ability to verify
compatible dictionary versions, obtain the correct version if needed,
and for the dictionary to learn on the fly.
