The <sectiondiv> element nests itself, so it can be specialized to create structured information within sections. Another common use case for the <sectiondiv> element is to group a sequence of related elements for reuse, so that another topic can reference the entire set with a single @conref attribute.
Because the <sectiondiv> element can only be used within <section> elements, use the <div> element to group content that might occur in both topic bodies and sections.
See appendix for information about this element in OASIS document type shells.
In the example below, the <sectiondiv> element is used to group content that can be reused elsewhere.
<section> <title>Nice pets</title> <sectiondiv id="smallpets"> <p>Cats are nice.</p> <p>Dogs are nice.</p> <p>Friends of mine really love their hedgehogs.</p> </sectiondiv> <sectiondiv id="biggerpets"> <p>Lots of people want ponies when they grow up.</p> <p>Llamas are also popular.</p> </sectiondiv> </section>
