Rulesheet Using a Conditional Rule illustrates a simple Boolean Condition that evaluates to either True or False. The Action related to this Condition is either selected or not, on or off, meaning the value of maxCargoWeight is either assigned the value of 200,000 or it is not (Action statements are activated by selecting the check box that automatically appears when the cell is clicked). However, there is another way to express both Conditions and Actions using Values sets.

By using different values in the column cells of Condition and Action rows in Rulesheet Illustrating use of Multiple values in the same Condition Row, we can write multiple rules (represented as different columns in the table) for different Condition-Action combinations. Expressing these same rules using Boolean expressions would require many more Condition and Action rows, and would fail to take advantage of the semantic pattern these three rules share.
