Token

A token, or sequence context is a context that represents data/variables that will flow through the scenario. Tokens are useful to handle variability and represent execution context when a scenario is running.

Tokens are initialized in initial sequences and can be modified, splitted or merged when entering or exiting transitions and sub-sequences using various functions.

A transition can have more than one token as input (coming from the upstream sequences).

A transition can have more than one token as output (going to the downstream sequences).

A fusion policy, called Token Merge describes the way the transition merges the upstream tokens.

A distribution policy, called Token Assign describes the tokens that are created for each downstream sequence.
