Other advantages related to the authoring process are the improvement about the completeness and maintenance of the possible rules. The improvement in completeness and maintenance are derived directly by the property of atomicity. Designers must decide the aspects and atomic rules in a way that they cannot be divided into smaller chunks with the four types of defined combinations. As each atomic rule specifies its own combination restrictions with others, then a designer has only to focus on each atomic rule and their possible combinations with others, but not on the many global rule possibilities (composed by several chunks) which can make to forget some of the possibilities and not being complete or making more difficult the maintenance.
