OneFS applies rules to a token sequentially. After OneFS applies all the rules in the list of rules, OneFS generates the final access token. You can, however, stop OneFS from applying more rules by inserting the break option in a rule. OneFS applies no rules that appear after the break option.
The direction of a rule and the order in which OneFS evaluates rules particularly affects how OneFS processes wildcards.
