The <ruleBase> Element
Definition and Usage
The <ruleBase> element groups a set of rules specified in <rule> and <compositeRule> elements. The specification of rules in NCL 3.0 was done in a separate module, because they are useful for defining either alternative components or alternative descriptors.
