>>-STATEMENT--+---------------+-------------------------------->< '-optional-item-'
If you must choose one of the items, one item of the stack appears on the main path.
>>-STATEMENT--+-required-choice-1-+---------------------------->< '-required-choice-2-'
If choosing one of the items is optional, the entire stack appears below the main path.
>>-STATEMENT--+-------------------+---------------------------->< +-optional-choice-1-+ '-optional-choice-2-'
.-default-choice-1-. >>-STATEMENT--+-other-choice-2---+-----------------------------><
.-,---------------. V | >>-STATEMENT----repeatable-item-+------------------------------><
A repeat arrow shows that you can make more than one choice from the stacked items, or repeat a single item. If a separator is required between items, it is shown as a comma in the repeat arrow.
