In the following example, rules allow up to four paragraphs in a topic, with up to two using each style. The rules are flexible so they can be used in any order. They allow optional use of the rule, but define a maximum use of two paragraphs based on each style.
The paragraph rules are defined as the number of occurrences, the location sequence, the allowed style:
0-2 | Flexible | Sub Heading |
0-2 | Flexible | Body Text |
Both paragraphs have been used twice. The rules are flexible and adjacent in the structure so they can be used in any order.
Both paragraphs have been used. The rules are flexible and adjacent in the structure so can be used in any order, including mixed occurrences as seen in this example.
This is because there are too many occurrences of the Sub Heading paragraph, a maximum of two instances is allowed.
